I have a destroked shortblock that i got in on some trading 4.155 Bore with 12.5 domes on a 64 cc head. Do these motors make decent power/torque it is going into a 1/8 mile heads up car that weighs aprox 2700 lbs
Should easily run that on alcohol. The cam I ran is a howards solid roller 264/274 .635/.630 lift on 110My goal was around 6.60 maybe 6.50's
Did the pro toplines have port wotk done? Where was your cam set to come on at?I had a 377 with a set of 235cc Pro Topline heads on it. It was a great running little engine. It didn't really like a lot of RPM like I suspected it would. It ran its fastest when shifted around 6800 rpms. It ran consistent 6.40's in the 1/8th at 3250lbs.
