Most common piston sold for the 300 is a firecrater style, unless ordered from IH. Then, you may find stepped head pistons that will be higher compression VS a firecrater. Firecraters are OK, they do help with torque due to its different burn created byt the turbulence from the firecrater. Keep the stock 300-350 cam in it, aint much better outhere unless your turning higher rpms. The science was there on the design of the SH-350 engines, they were low compression to keep fuel economy in the fields, but,, add compression,, and it will really come to life. I like aluminum, rather than chrome,,,, Dont know why,, just do,,,,, LOL! Rejet the carb, change the mechanical advance springs in the distributor, (under the points plate) with springs from a Chevrolet HEI distributor, or get a Recurve kit from NAPA, then you get 3 sets of springs,,, I use the second heaviest springs,,,, seem to work the best,, it helps with throttle reponce, and a bit more accurate timing upon acceleration. If your engine makes 150 psi of compression,,, your looking at 45-48 hp pretty easy. 175psi and up it will e in the low 50's. Hope this helps,,, KEEP THE STOCK CAM!!! ChadS
