[QUOTE="atafonso, post: 603804, member: 23592"] I would expect 25 psi at idle when hot on a properly rebuilt engine with all tolerances as they should. Your dynamic compression will be to high for this cam, plus you using 94 barrels which produce a lot more heat. Oil temp is one thing, head temps is another. Your cylinder pressures will be too high. I am just giving advice, take it if you like. 40 Dells are great, but change your vents to 28 or max 30 as the 32's are too big for your combo. There will be no benefit whatsoever using them due to the cam stoping to make power rapidly at around 4k. They can be more tricky to tune due to the intake valve size too. This engine will be a torque monster, but will not make power up top as it would if it had a different cam. Abel [/QUOTE]
