383 stroker - 12/01/13 07:19 PM
I have a 383 block and looking at some stroker combos for my next build. My current combo is a 470 that has ran a best of 5.73 in the 1/8th so I do like the 3.9 crank. I am looking at the following:
1. 3.90 stroke, 6.700 rod and 4.310 piston for 456 c.i.
2. 4.25 stroke, 6.535 rod and 4.310 piston for 496 c.i.
Heads and cam are Indy SR's with a mild port, cam is 661 lift in and ex, duration is 275 at .050. This is what is currently on my 470.
Reason for the 383 is I have one and they are readily available.
Car weighs 2500 with driver and has a powerglide trans. This will be a back up shortblock for 2014 and will be used for the 2015 season.
Anybody running these combo's?
