Will trickflow heads on a high compression 306 with track heat intake and custom cam be able to run midd 11's? Would this combo be just as good as afr 165's, rpm intake and custom cam?
Custom cam only does so much more, I'm sure you could make more power that way, but my opinion is that 11's would require larger heads. I'm leaning towards 185 or more to get you to your goal
300 rwhp can go 11s with a good suspension and some good driving. To go solid mid 11s, Im going to say a street car will need 350 rwhp or so. I would say the TFS heads and track heat intake will go mid 11s on a higher compression 306. You might have to have the heads ported, but theres definately enough to do it. There are plenty of 300-325 rwhp TFS cars with stock bottem ends that a high compression motor and custom cam should make the power to go mid 11s. The right suspension some low 1.6 or high 1.5 60's and your in!
Speed-pro 306 pistons with 10.5:1 compression? 4 valve relief type? -2cc? That is what I have in the works, it only calculates to around 9.8:1 with TFS 61cc heads. You will be very limited to the cam choice due to piston to valve clearance with an inline piston on offset heads. I am pulling out the pistons if not selling the whole shortblock because of it.

2 valve not 4. The part# on the piston read L2466F 30, but when I went to summit the only part # I found was L2488F 30. So maybe I misread wrong or something is fishy. The guy who I bought the motor from said he had 10:1 comp with edelbrock 61cc heads. I was gonna do some work to get the trickflows down to 58cc so it would be around 10:5.
i am also running a 306ci with a trickflow efi manifold, stage 1 trickflow cam, tfs heads 61cc, 24lb injectors, 75mm throttle body, 1.6 rockers, keith black pistons 9.8:1, 190lph fuel pump, 373 gears. about what horsepower should i be in the range of and what whould i run in the 1/4 mile?
