So, finally getting around to building a "beater" engine to develop my race car project (been idle too long). The idea is to build a reliable, decent engine that's not crazy expensive to sort out my car, then put in the expensive engine when the chassis is ready. I will only use race fuel with this engine.
Basic specs are:
Now, the question... should I source 0.220" or larger shims to drop the CR at the expense of deck height? A shim of 0.220" will drop the CR to 10.4:1, but raises the deck height to 0.050" Thoughts? |

Sump extension: check
Windage tray: check (see attached) I've got 2 stock ones and this modified one. Aside from the windage tray, are you talking about additional bits to reduce the sump volume? Clever. We did some work on that for a recent project... it can yield benefits... we had to test the crap out of it to make sure it was durable and proven before we ran it. This particular engine is about reliability with decent power, not SCCA-optimized performance (it's not legal for SCCA) to sort the car out and then figure out where to go next with the car.
