Re: Dart Pro1 227 Platinum vs older 227

The current 227 is sold CNC'd only. I just haven't found anything to show how much better they are than the old 227s.
Thanks

Re: Dual plane 4500 intakes, C454 vs torker 4500

LOL. I had one [single plane] on an olds, it was ok, but the pontiac guys said that they were anything but torque.

Dart Pro1 227 Platinum vs older 227

Hello all,

I've searched here and elsewhere, and I can't find much on the older 227s. Only that the later were developed with wet flow work and are superior.

Anyone have flow data on the older versions? Or, direct comparisons?

Thanks.
Dave

Re: BBC dual 4 Barrel dual plane intake vs a Victor JR>

I like the idea of the divided spacers that you showed. They would allow fitting 800s w/o "ruining" the manifold itself.

Although, Mr. Gasket does not show them on their site. Mill out 4 hole.....

Re: Dual plane 4500 intakes, C454 vs torker 4500

Thank, 1980 RS,

I didn't know that they made a dual plane 4500 oval port! I have the C454 [rect]. I'll have to pass on yours, I'm intake heavy! LOL

Oval and rect RPM air gaps
C454.
Dual quad rpm air gap [rect]

They sure liked the Torker moniker!

Re: BBC dual 4 Barrel dual plane intake vs a Victor JR>

Thanks, F-Bird, Interesting thread. [the six pager] I've never liked the AFBs, but I do have a guy trying to chase my down a pair of 800s. I'd prefer AVS' though. I sat two QJs on it, the front one normal, the rear one backward. They clear and have the same bolt pattern! Why do i think of goofy sh*t...

Re: Small cams on 106-108 LSA’s

Lunati will grind their shelf cams, or custom [you pick lobes] on non shelf tight LSA, same price as their direct price for shelf cams, which is cheaper than summit/jegs etc price. They just did me a 292/292 - 241/241 [Voodoo 241/249 shelf cam's intake lobe] hyd roller big block cam on a 105*+4, .36...

Re: BBC dual 4 Barrel dual plane intake vs a Victor JR>

Hello All,

Old thread, but has anyone run a dual quad air gap? I acquired a #7522 square port version, long discontinued. [oval port only now] I figured 750s or 800s.

Vizard wrote positively about them. A fellow at Edelbrock said that they really trounce the old 2x4 intakes. [C66?]

Thanks.

Re: 502 GM crate engine Gen VI blocks - all same max bore?

I had a reputable machinist/engine builder peek at it. He said bore it to fix the rust and run it. No sleeves.

Thanks to everyone.

Re: 502 GM crate engine Gen VI blocks - all same max bore?

Gents, I did plan to have it sonic tested. I just wanted opinion of how over-safe that was. What i read about GM going to 4.600" on max bore was wrong, that must bre on aftermarket blocks [p292 chevy perf catalog].They still list 4.500" The missing chunks are apx 3/4" x 3/4", facing each other, so o...

502 GM crate engine Gen VI blocks - all same max bore?

Hello all, I bought a std bore Gen VI 502 block, casting 319165956. I'm not sure if it is the latest version or not [which afaik, is part # 19170540 with same casting #]. It does have the bolt boss in the valley for the dummy oil pump shaft, and the std and corvette clutch ball bosses. GM lists the ...

Re: SBC intakes Holley 300-25 vs 300-2

Do you need a mini tig torch to get at the side that is outboard? Or will a flex head #17 work?
Thanks
