23 Dec 10 Dart iron eagle 331 idle

This is the new motor, soon to be 88MM air/air. It’s a dart iron eagle 331, pro comp heads, mechanical roller etc. Soon it will get dyno’d N/A just for grins, I’d like to see real world gains with the turbo.

Question by Winni-v: Has anyone ever used dart iron eagle heads?
i have a sbc with dart iron eagle heads. i ordered a top end kit from summit 01110003, and with those heads the cc is 130. the problem im haveing is finding a cam that is comparable. summit reccomended a lunati cam LUN-60105LK. well i wiped out a lobe on that cam. im useing the kit on a stock sbc 355. will that kit even work on that block. curious to know what i ned to do to get everything to work together, also have flowtech headers, 750 holley carb, scorpion rockers, stock 350 pushrods. any suggestions

Stock pushrods are not going to hold for long for one thing. If you wiped out a lobe on a Lunati cam then you made a mistake somewhere in your assembly. Either far too much tension on your rockers(0 valve lash and then way too far beyond), or your geometry is off somewhere. The geometry being off is most likely since your now running a different set of lifters and rockers.
Bite the bullet and step up on the pushrods. Before you do you need to figure out what length you need now.

P.S. That is WAY too much carburetor for that engine and cam combo. Step it down to a healthy 650cfm. Your throttle response will increase in a HUGE way, so will your power and torque. Too big of a carburetor will flood an engine at the snap of the throttle, and then lean it out to crap.
