I have a 1973 400 block (630) that I want to build to 550-600hp for the dragstrip only. So far I was thinking after all my research, is to stroke the engine with Trickflow 240 heads. I read AndyF's Max-Performance book and was thinking 451 or 470...or maybe go right for the 512???
Can you more experienced racers give some suggestions of a build that might work for me? It looks like my budget is about $10K
Below is an idea for a build...
- 440source stroker kit with 2.200 BBC journals
- compression at 11-1 or 12-1 (high octane pump gas or 110 race gas)
- 590 mopar performance flat tappet cam
- Trickflow 240 heads
- single plane intake with holley carb
I'm thinking about the same thing here except I have a 440 crank already cut for a low deck so...451 is the deal for me though a 470 is still tempting. I thought about the 512 but in a low deck I don't think I like the short rod needed. Also, with a 512 I'd probably run the 270cc heads over the 240.
Where do you want the power band? Seems one of the biggest changes with going with a big stroker is what rpm you will spin the motor.
