worked out a combo with my engine builder:
- 250 xflow
- standard crank (knife edged)
- rods (shot peened, crack tested etc)
- 289 rod bolts
- wade cam (profile: 1069)
- ACL race series pistons (8cc dish)
- HF5 alloy head
- head has been ported extensively, running 1.85 inlet valves, exhaust cant remember whats in it.
- cain 4 barrel manifold
- gas research 400cfm throttle (might have to rebore it to 440cfm later on, will see performance on dyno)
plugged the exact figures I have at home into a few calculators, should be around the 10.2'ish static comp.
cam specs:
lobe lift (ex .297 / in .296)
timing advance (ex open 79, close 32. in open 38, close 72)
duration @.50 (in / ex 222)
valve lift (ex 0.514, in 0.512)
lobe seperation: 110
Info: reasonable idle, good midrange, 2500 stall
what power figures can I expect with this engine combo? opinions please?
I was going to go the 200 route, but a few people have said to stick with a strong 250.
