Head and cam selection help for 440

so im not sure why i wouldnt see nice gains by doing the same thing..?

Jim’s “Pop’s” 440 test starting point was with heads that flowed:

I'm guessing we'll start with a Comp XE285HL and the 346 heads with the stock 2.08/1.74 valves. They're flowing,

.100.............88/59
.200...........164/114
.300...........210/158
.400...........236/194
.500...........259/211
.600...........270/224
.700...........280/234
(Stock 452’s flow low-220’s)

On an overall combo of:
.030" over 440, 8.9:1 compression, 850 Mighty Demon, Edelbrock Performer RPM intake, 1.6:1 Crane Gold Race rocker arms, Comp XE285HL cam, our ported 346 factory iron heads with stock 2.08/1.74 valves.

Just off the top of my head.....Porting your stock heads to that level, swapping to that cam, swapping to 1.6 rockers, and the required pushrods would be roughly 2k.
That gets you to just under 500hp(like what they saw)....... if your carb is as good as the Mighty Demon 850 they tested with.

A set of fully ported EZ’s flowing in the 350 range will be in the 3k range, not including the other parts required to use them.

My comments about “you” not seeing the same results are based on you saying the TF heads aren’t in your budget.

If you’re paying for upgrades.......and those upgrades include new heads and/or head porting...... 2k doesn’t get you very far in the BBM world these days.
