Really? Full time now going on 15 years. All I do is port heads. Have them all over the world. Have National records. Just did a set for Reher last month. Shipped two more sets of Super Stock heads to FJ Smith. Did a set of iron heads for Scott Schraioff recently. The world is bigger than NJ.

Just sayin.

There ya go...…..

if you say so Chad, but I've never met/spoken to one person running your heads at any national event, divisional event, or bracket race. The aftermarket performance world is bigger than the internet forums.

Just sayin.

Butthurt in 3.....2.....1......

Now everything is back to normal.....


and I kind of like it....LOL

yes, Rich it is with you being you.

Yeah, but you don't build engines, you buy them from Sunset. I build engines so I understand a 383 is a stepping stone sbc. The OP is already concerned about crossing around 7000 rpms. This tells me he's already out of potential for rpm as far as durability. Bolting AFR 210's adds maybe 20 hp. It's time for exponential growth more cubic inches + torque + the potential for RPM.

Your local engine builders suggestion ^^^^ exponential growth.

I won't be buying one of your Build for the Future engines,,, that's for sure!

BTW I thought you were a tranny builder???
Do you build tranny's for the future too?

I'd be a little more concerned if you were apart of the new niche market, the homeless.

Obviously you have NO sense of humor in this time of crisis when everyone could use a good laugh!

Do a Youtube search for Quarantine Confessions by Rodia Comedy! Maybe you will get a kick out of that.

Ed is still laughing!

You probably won't find many in SC.. I really don't do much BBC stuff. But go to a truck pulling event, or tractor, or X275, might be a different story.

I'm not here to argue. I know to some I will forever be an internet porter. But I can't survive without results.

AND, "I have no issue with Chad and his work "looks" nice" is probably the nicest thing you have ever said to me. So thanks!

And glad to see your kid tearing it up. Yea, I pay attention.

Chad, my circle of racing friends is far greater than just those we compete with in S/C. That said, You don't need to prove yourself to me, you do what you do and have your niche. Besides, you like Yorkie's so we good. Thanks, he is and for the record, my heads ain't been touched by any head porter, they are OOTB.

Chad, What do you suggest for the OP? I respect your opinion. Some of the others not so much.

By the way Fatboy I sent you a private message.

Can I get some info from you guys on what head would work best for my setup?

Current setup.
.040 over 383
13/1 pistons
Comp 294cam hr 243/248@.050 .540/.560lift
Promaxx 190cc heads
Ported victor jr intake
850cfm Holley Xp
5500 ptc 8”
4.30 gear
2540 lbs

Truck runs 10.50s @ 125mph 1/4. Rpm is 6800-7000 threw the traps

I’m looking at 210 or 220 AFR heads

I have a hr now but plan to upgrade at some point to solid roller.

Questions are:

which head will work best on a 100% drag truck?

Should I get the head set up for solid roller now?

If I plan to put 200 shot of nitrous on it from time to time just to play would I need to do anything differently when ordering the heads?

1st ? on the top. See if the current head could be ported to better fit the motor. Too small IMO & I looked up the flow numbers, not adequate.

General motor combination looks like it was set-up more of a street/strip deal other than the compression. The converter/gearing looks to be strip.

1st ? at bottom, if this is 100% 2540 lb. race truck treat it as one.

2nd ? at bottom, Yes, get a solid roLler in it.

3rd ? at bottom, I wouldn't do anything different in the heads.

Just my opinion.

BTW, that engine builder kept me from making a big $$$ mistake on heads. We redid my combination without spending a lot of $$$ and the car picked up over .50. Good luck.

Thanks man. I just had the bottom built. H beam, steal crank and forged pistons. Race balanced for 7500rpm and 800 hp

The heads I have won’t handle a bigger cam so I was thinking of upgrading the heads to a better set with a bigger cc intake runner to match what I do with it. I had Originally bought those heads for streetcar

Be careful here, a solid roller cam with the same lift and 8° more duration will reduce piston to valve clearance vs the hydraulic roller cam. Even with the same lift and duration the piston to valve clearance would be less because of the quicker opening and closing rates of the solid roller vs the hydraulic roller.

If the piston to valve clearance is close now, you could get in trouble quickly......

Fatboy81. I have reread your post a few times and the responses your getting. Upgrading to a set of AFR's set up for an even mild roller you will shoot your self in the foot . The spring pressure from a solid roller and a HR are much different. your current HR roller, IMO, will not be sufficient to flow with bigger heads. Heads are where the power is made, but with the right engine combination. Ed, Brian and others can weigh in on this but IMO, going to a bigger head will REQUIRE more cam. Then you have the issue of converter stall, flash etc. Leading to a possible gear change. See where I'm going with this? AFR makes a great head, used them on my S/C car for years and don't get me wrong, I'm not trying to steer you away from them. But you'll pay well over $2200.00 for the set your after. Then you will need a good head gasket, my personal favorites are Cometic, almost another $100.00. For about half that you get a good mild roller cam, lifters and upgrade your current heads to handle the new cam. Good Luck.

This, is the spice I’ve missed on DRR. Everyone pulling it out, showing their skill sets. lol
PS Top38 is very knowledgeable as well as Chad and Ed.

Nobody has said anything useful yet, other than the OP informing of a 7500 rpm limit on the engine. It might be good for that, for a bit wing wong ching chong crank and rods.

He still hasn't said what his goals are other than spray it with 200 hp on a plate here and there.

If that's the case put a bigger intake valve than a 2.02 and port the heads. Solid roller camshaft a hair bigger than 560 and spread the lobes 110-112. Tighten the converter 400 rpms.

Simple.

Let's start over here,,,

first you still haven't stated what your goals are! So to provide you with advice on what you should do is just an assumption on what we think you want to do. And want don't mean you can afford the added costs.

Your current combo shows it is making around 425 HP based on your performance which is well short of the capacity of your heads!

Your current cam is s fat piece of low hanging fruit with regards to making more power.

You state that the heads can't handle a bigger cam, explain this statement. And BTW I don't agree here. Changing the cam to a solid or solid roller just requires new springs and maybe retainers. Don't know what the installed height is so I can't say what your max lift can be but Promaxx lists flow to 600 lift! So I'd say there is room for more lift, probably in the 650 range. Changing intake valves to a larger 2.05 or 2.08 will likely will hurt those heads! The intake flow they list on their web site will support 500 to 525 HP as is, that's a solid 75 more than you have now! So for reasonable gains, the heads are not the issue! Yes you would need to check valve to piston clearance but adding lift alone does not effect this, changes to duration and lobe separation however do!

Your carb is too big! A 750 would be but a lot better with room to grow.


For a bracket race deal and to gain some realistic HP for the most bang for the buck!, Change the cam to a solid lifter deal or solid roller that fits your current combo! If you pay attention here and the rest of your combo is good, you can get your truck's ET down to the 10 range. (500 hp is 10.0 et's) How close depends on the rest of the combo along with tuning! Also you don't need to turn that motor to 7500 to make 500 HP! Peak power will be in the 6600 range at 500 HP.

You got two pieces of BS with one statement of truth sandwiched in the middle here.

SIMPLE!

Exactly what? Top 38 needs to stop drinking the bong water possibly!?

How do you go faster with less RPM? You guys are some funny mofo's!
