deminkj Posted May 21, 2006 Report Posted May 21, 2006 (edited) I dropped a +4mm, +5mm longrod crank into my +.80 engine. took off great, but i think the space leaks coolant and i have timing issues. Anyone know for sure if this will run right with a stock stator and timing? back fires/whooshes- and anyone have experience with the gasket spacer problems? thanks!!

2bzy2p Posted May 21, 2006 Report Posted May 21, 2006 (edited) well lets see your port timings are off if your runnin the same set of cylindars that are ported for your old 350 thats your main problem. you need to get them ported to the 4 mill now Edited May 21, 2006 by 2bzy2p Quote
cdwood37 Posted May 21, 2006 Report Posted May 21, 2006 Or you have to buy the spacer plate, but for max power you should get them ported. Quote
