Hello BILL,
I bought a 514 crate motor. Looking at the specs, it is intended to be a drag strip piece, not a primarily street item. Certainly not if it is going to be driven as a (pretty much) daily driver.
The 9.8 nominal compression ratio means I can keep the reciprocating assembly as-is for street use.
Having observed that, here's what I did:
Intake: remove Dominator-flange single-plane intake, install Holley-flange Edelbrock Performer RPM 460
Cam: Remove solid roller unit and triple valve springs, install Crane hydraulic roller unit, double valve springs
Pan: remove pan, install Canton road race pan with correct pickup
Sell removed parts.
Anyway, those are the highlights. I'm also adding an 850 Demon carb with vacuum secondaries. I paid to have the engine totally torn down, inspected, some porting on the heads, cleanup of the block, rebalancing etc., etc.
I have posted my experience with the rods elsewhere on this board - since Ford Racing has supposedly gone to the Eagle-like rods, that should not be an issue any more.
Having said all that, I've never heard any of the above run! The engine is now ready; the rest of the car is a couple months away - I'll post the results when they are available.
Bottom line: build your engine to suit yourself
One way of looking at things!
Tom
PS: If the hood scoop won't fit, even if I make it an inch taller, I may have to get a Torker II intake.
