Good buildup to reach 400+ horsepower 302 truck

Stock heads have 58cc chambers, I think. Twisted Wedges have 61cc chambers. On a stock bottom end, you'd be looking at dropping .25 or so. I use Dyno 2000 too. Sometimes, the numbers seem way off to me, but other times they seem right. I haven't pinpointed exactly why yet either. I'll see what I get with a B303 in a stock 302.

Stock heads have 64cc chambers. My Canfields have 58cc chambers, now I have to run super unleaded with my timing advanced or it pings but the extra HP is worth it.

We must be inputing different numbers for our components.

This is what I have for overall:

401hp @ 6000rpm and 392tq @ 4500rpm

This is my flow data on the twisted wedge:


This is the cam data for the B303:


I got all these numbers from the manufacturer's websites. Note that a lot of the values don't match the included files that came with dyno2000. So if you're using those, then that's where the discrepency lies. I suspect those ones to be in error.

Also the stock 302 with just the B303 cam and exhaust gave me 291hp @ 5000rpm and 358tq @ 3500rpm
