Old brodix -10 heads on a 406 keep them or buy new??
Hay what do you guys think, new heads or keep the old??? It just wont run like I think it should. here is wat the motor has. the heads are old -10 spread port brodix heads flowed buy rons racing, 2.10 in 1.60ex (intake gaskets felpro 1206). the cam is a lunati 276/284 at .050, .640/645. victor e itake ported to the heads, flat top pistons witha .014 deck, .039 gasket, heads have 60cc chambers, 850 carb, powerglide trans with brake, 5100 stall converter. the car is 8" tire 2700# vega (with me). 26" tall tire with a 373 gear. the car run 11.20's @ 118 to 124. bad short time of 1.7's (not spinning). I have used 3 dif converters this one is made for the car. I have used a rpm airgap. I think the car should run in the mid 10's. It feels like a dog.
More info . I had the converter make to stall with my combo at 5100rmp on the brake. I told the guy it should make about 500hp. the convert stalls at 5150 on the brake. Am I off here?????? I dont know what else to try. Thanks Billy C
