Thread: Finally Building the 350 this week... what do you think about the setup?

Yup, way too big of runners, and way too much cam. Also, you've said nothing about ignition components or a distributor.... Personal preference, but I much prefer a vacuum secondary with an automatic transmission for street use. With a secondary spring kit and some jetting it is easy to match the timing of the secondaries opening with the stall of the converter and the cam coming in on the sweet spot. Double pumpers IMO work best with standard transmissions and/or on the drag strip where maximum performance is the issue and not driveability..... And a reminder, higher converter stall speeds in traffic increase tranny temperature, make sure you also install a good transmission fluid cooler....

I think the compression ratio on that motor might be too high with flat top pistons and 62cc heads. If you could give us information on the piston to cylinder deck clearance as well as the valve relief volume and head gasket thickness/bore, we can give you a real compression ratio number.

What?He never states what his comp. ratio is.Either way he does not have enough for the cam he listed.
