340 the hard way; Stroked 318

The MP P4529710 Forged crank was indeed designed to clear the 365" rule and better compete with the small block bow ties. I did a "Google" and came up with some interesting blogs behind the P4529710.

I also did purchase the SFI Flex Plate, but didn't realize that it requires a larger bolt to secure the converter.....damn....

I have also decided to regrind my existing roller camshaft for my '85 Block that came originally with a roller.

Cam Specs - Int - Exh

Dur @ .050 226 - 230
Lobe Sep 111
Valve Lift .474 - .474(@1.5)
valve Lift .502 - .502(@1.6)

I have the stock Magnum rockers @ 1.6 and purchased the matching springs(P4876062) for the above cam.

I kept the same lift but a bit more duration on the exhaust side. I have performed a mild port on the intake, but a more aggressive port on the exhaust. So I think the intake to exhaust ratio is more equal requiring less lift and duration otherwise.

Now on to the pistons....

I plan on zero decking with the 3.51" crank and moper was kind enough to offer some suggestions. Measurements on a stock block with a 9.599 block height indicate that a compression height for the piston should be 1.721. There are ready available pistons that are 1.741. Is it possible to shave 0.020 off the top of the pistons or am I playing russian roulette? I don't plan on revving it past 6K and everything will be balanced.

BJS Racing has lit a fire under my butt with his post. 13 second car with a 370cu in. with a 280H. Tell me that wasn't with a 2900 lb car and and 4.56 gears....!

Thanks again guys for your input....
