I was wondering what you guys thought this combo would do in the 1/4 and what you think the HP and TQ would be.

010 block bored 60 over

062 vortec heads shaved .018 (i think that makes them ~61-61.5cc chambers) The exhaust side is ported by me (vavle bosses look like bullets and all casting seems are smoothed with a nice smooth short arc) and polished. The intake sides have knifed valve bosses with gasket matched intake ports. The springs where upgraded to LS1/6 beehive springs good for .550 lift. Stock 1.94/1.5 valves.

Lunati VooDoo 60103 cam 227/233 degrees at .050" and .489/.504 with my 1.5 rockers.

TH350 trans with 2300-2500 stall

stock 10 bolth with 3:73 gears

also will be running 26" tall MT et street non radial

Should i run 4:11 gears? This is just a weekend car to race at track and eat rice on streets

 

3.73 should be fine with this combo. If you're still using the 10 bolt you really don't want 4.11's as the teeth on them are very small.
