Anyone here using or have experience with the big block flat tappet 74cc heads. According to the “specs” they say spark plug style stock..?? As in straight..?? Also no mention of stock rockers and shafts..?? If anyone has any info it would be much appreciated…Thanks. Swingn’

Research the big block heads because I don’t think they are common Edelbrock heads. Pretty sure the are Victor copies and require off set rockers.

I never bought a set so I’m not positive. Just recommending you make some phone calls.

At one time speedmaster sold big block rpm copies, and Victor copies. I don't know what they sell now. The Victor copies DO need offset rockers. Speed.aster sells those too, around $300. GOOD offset rockers run from around $900-$1300.

The big block heads take an offset rocker, something like .630 or .650. They have raised exhaust ports. Kim

I have a couple packages coming the other way, Canada to Pa. listed at 42 pounds each at a cost of 79.00.

That’s about what it costs to ship them across Canada.

I have no idea why they don’t offer an Edelbrock big block copy. It would probably really out sell the one they offer.

Idk either. I think the Victor copy flows a fair bit more than the regular Eddy. Kim

yes it does but most guys can’t use it. Sometimes to much of something isn’t a good thing.
