yeah, now that you put the correct cam specs up the cam is ok. smaller then most run but not bad. Actually very close to the cam in my 11.7/1 347 that is in my Nova.
My cam is a futral grind for a 383 that a friend had. I put it in because i got it for a $100.

Car was on the dyno today, hot and humid day, put down more power, and was on an eddy current dyno to boot. Asher can explain.
I've built quite a few combinations using these parts on 402-408 engines, and i've had people overtime feel the need to replace my parts with the latest internet sensation and seen the results.
TFS 225 CNC heads i've seen best results with far as trick flow product goes, in terms of port size. 235 heads on a 4.000" bore i've only seen worth a couple more horsepower even with touching up the valve job. 225's have better port velocity, will only lead to better driveablity.
Camshaft, 239º LSL lobe i've seen doctors 240º@.050" FWIW, splitting hairs but thats the lobe I was looking for. If my baby cams can bring 500rwhp (as they have; or the potential for 500), I'm happier with that then running larger duration to only be under performing.
goal for this was to be within a budget, 500rwhp, and have driveablity we're getting closer to that.
