well i want to have a fun street car with some occasional track use (both drag and road course) and no i was looking at the 225cc patriots for 900(or would the 185cc's be better for this application?)with an edelbrock rpm series carb and intake and i know #### all about cams so i wouldnt really know what to get in that department but i was just curious as to what kinda power it would put out?
I know all the big head choices are out there. I want to put some things into perspective. Not too long ago, to have a 215cc or larger runner required off-set rocker arms and off-set lifters. They are huge. If you do get the big heads they will work better on a mild motor with with a smaller cam. They heads flow so much better the bigger cam is not needed to move the same amount of air.
I would steer you to vortecs or after market vortec clones. That is unless you already have the intake you want to run, then I would steer you towards any head in the 170-200cc realm. I have had lots of luck with the RPM Air Gap intakes on big and small blocks. If you can get aluminum, they are lighter, can be repaired, and will allow for almost a point higher compression on the same fuel (like from 9.0-1 to 10.0-1). Some TBI motors were hydraulic roller cam'ed, not all, also, not all of them have a provision for a mechanical fuel pump.
You can get the hydraulic roller stuff pretty reasonable now too, lasts longer and makes easy horsepower. GM Performance Parts offer some cams, the LT4 "hot cam" gets lots of press, but is designed to work in harmony with the ECM and fuel infection, so, if does not have that 'big cam' sound or idle.
