TR-5 Tunnel Ram

340 8bbl my motor will be around the same as yours but with some more compression and a higher stall. What do you have done to your J heads? I have a set of 360 J heads and im putting 2.02 intake and 1.6 exhaust valves in them. Forgot which cam im installing in it have it saved at my computer at home (out of town for work) but i believe its around .556 lift (belive sweet spot is 3400-6800ish) which is pretty much the same sweet spot as the TR-5 (3500-7000+ is what edelbrock told me when i called) So that should be a pretty good match correct?
