For the second time, I just picked up my stroker engine from the machine shop. Had a bad failure shortly after start up last year. On the highway a freeze plug came out and toasted the engine. There are other threads on that. The machine shop made good on the engine. Repaired the burn through of the head and put it back together.
He said today the engine compression ratio on this engine is 12.7:1. It is supposed to be 10.6:1 with the kit I have. On Summits site the compression ratio calculator comes out to 10.97:1 and 505 CI.
I will put all the specs I can below.
440 source, 440-512-5060 kit
440 block bored .030 over.
Zero deck.
Pistons, #5060, are -17 dish
Crank is #44042506800-6, 4.250" stroke/7.100" rod
Trick Flow PP240 heads. 78cc
Head gaskets are .036 compressed
So what is it really?
