Stroker Combo Questions

Chassis: 69 dart, mini tubbed, frame connected, cage, RMS alterK.

Hood: glass 6 pack

Heads: Performer RPM done by Jim Laroy. 340 something intake flow. Not sure about port volume.

Cam: Solid custom roller but the one we discussed was for my 440. Not sure how it would work in the stroker. It is 250 something at .050. 112ls .650ish lift.

Goal is to go fast. I hate putting a number on that because then you only shoot for that goal. I want the fastest true street car around. Initially the goal was to go from my current 11.70's into the 10's.

Budget: I don't know...? I already have the most expensive parts of the engine paid for. Heads, block, cam, intake, carb. So not much left.

Sorry - I thought you only had the top end and possibly the camshaft.
The port volumes to me are important. Bigger volume will be softer on a shorter stroke combo. That's not to say they'll suck - just that if you have the heads ready to go - you might as well match the displacement to them as closely as possible. Jim will have that number - or you can measure. IMO the stroke is the primary concern, the piston hieght is second. The ease of fitment is next. Rod ratio doesn't mean much at this point but once the stroke and heads are known that ratio will affect camshaft selection. I really liked the B wedge 496 deal I just built, but it might be a little much for the heads with that cam. Again I'm being general here - but something in the 470" range IMO would probably be a great street/strip package, and able to go to the high 500s on cheap pump swill with big torque and a flat torque curve. You could get more with a bigger camshaft but you need it to be comfortable idling for a while and not using huge spring pressures. You basically want a bracket package that isn't going to need yearly teardowns or refreshing - so I'd stay with a taller piston, shorter rod, milder compression, mild camshaft.
