One of those numbers can't be correct, or else you are running the 1/4 on a mountain and the 1/8 in a mineshaft...

Just to compare cams with what brian comes back with here is mine.

Engine builder specified a crane cam #138951

this combo should be faster in my opinion. I have considered moving the cam from -4 degrees to +4 degrees and see what happens.

I wasn't going to say anything, but my first thought when you posted your ETs was that it is really slow for a 18 degree, injected 632.

I also run an injected 632, with conventional Pro-Filer Sniper-X 375 heads. It made 850/1020 on the dyno which isn't much. I've never run it wide open, but in Super Comp trim I have been 146 in the 1/8 and 182 in the 1/4. The way I run my stop, I wouldn't expect those to change much wide open.

My 565 with the same injection and heads, ran roughly the same as what you posted. I am nearly 100# lighter.

My cam in my 632 18* motor with Injection is a LSM ID# AE290
867/850 on a 115 LSA
67* of Valve overlap
It’s a 4/7 and 3/2 swap cam
