I have a 1976 360 engine. I am planing to prepair it for a swap with the damaged 340 in my Cuda.
I have striped down the engine to check the condition. It looks quiet OK. Chrank and bearings is very fine. Cylinders shown very little wear.
I would like to increase the performance so it will produce around 400HP.
Shall I keep the the original pistons and just change the rings and do a honing of the cylinders ? Or should I change pistons to obtain higher compression. Is it at all, vice to install new pistons without reboring the cylinders ?
What is the compression rate of the original pistons ? Will they work well with the 340 or edelbrock alu heads ?
What cam shall I choose ?
Have checked the internet for engine rebuild kit
Any recommendations ?

Many questions, Thanks to all answers
