I would suggest a chassis or hub dyno if available near you, many of the top cars are tuning on these dynos today.

Totally agree.

Ed, check this out. This is the profile they were using in 2008-2013 range for the 041 heads. They flowed 240@.500 and 260@.900. The new stuff flows 260@.500 and 280@.900. This cam has 68º of overlap. All going out the exhaust, exhaust ports were nasty.

I’d have to run some simulations but I don’t like the events and the resulting LSA, every sbc that I’ve spec’d a cam for always ran quicker with a tighter/narrower LSA.

The cylinder head's combustion chamber has a lot to do with LSA's also!!! Take your typical SBC vs as LS motor, big differences what they want!

I know and agree. he ain't running LS heads rather straight plug Edelbrocks

They allowed the angle plug for a LT1 now. Which is good because the plug is in a much better location.

SO HAPPY! Finally got the TH200.. It has a new billet brake that has a clean neutral like a XLT Coan. Take the input shaft and spin it, keeps spinning..

Also got these. I have a good customer that just made them for me. WAY too expensive. I probably would never buy them, but gifted is awesome!

Nice transmission, what planetary gear ratios?
