Just noticed this post. I ran an alternator in my 1968 Impala BBC 396/325 I/S car back in 2004. Never tried without the belt. Damn if I could have picked up that much I would have tried it. I liked running the alternator felt batter keeping a full charge in battery plus I ran 7 AL MSD box which will be same in my 65.

Will, you do realize that you must have the alternator belt on in stock eliminator ? ....M.J.

Thanks M.J. for the heads up. My computer too slow to download the whole NHRA rulebook, I'm just going on what I know! Maybe that's the problem. I do remember having a larger pulley on my alternator but it would not keep the battery charged enough. I did not want to rely on my generator. Seems like a lot of rules have changed since 2004, much more liberal.

Mike, didn't mean to hijack your thread! Thanks

The combination in this car is the 262/165 which in '75 had to use the tiny 1.09" Venturi 2GC carb. This puts a major challenge with this combo. This is the exact motor I ran in my Monza stocker sans the small carb. As a '76 I was able to run the 1.18 venturi carb such as what Briane Philbrick runs on his in Canada. That .09" difference makes a world of difference in the performance of this tiny V8.

Thanks Joe, for comparison though, a 302 runs 1.08 and a 351 or 400 ford runs a 1.21....so in relative terms, he ain't so bad! LOL!

Cool stocker though.

The air horn on the 2Gs is very small and restrictive not like the motorcraft 2Vs. Big difference.

Does anyone have REAL flow numbers for 2-bbl carbs?

True enough.It's a small carb.Same one Billy uses on his 307.
It feeds 45 less cubes though.
Less cam, but a bit more compression.
30 hp less , rating wise
It ought to run a half second under in decent air with headers, converter and such things maxed out......in my opinion.

Sooooo the new alternator setup worked well, but hard to tell if there was a performance pickup. Ran an 1/8 mile CCRA race and the air was really bad, 90+ degrees and very humid, first really bad air I have run in. One P/SA car that normally runs mid/low 8.0's in reasonable air was running high 8.2's, and I was at 9.56 twice. Took 2 degrees timing out and went slower. So I'm guessing based on the P/SA car I was losing at least .2 which would have put me at 9.36 in reasonable air(9.50 IHRA 1/8). No races coming up and weather is HOT so going to concentrate on header and converter mods for the time being.

Mark, the current headers are Hooker Headers#520-2451(several pics on JEGS) 1 5/8 prim 30" long 3" collector with 18 inches added. I don't think these are totally 'equal length' either. Test was to see if the merge stuff worked on the 'old' headers before I hacked up the hookers. So not going to hack them based on the test. And yes I am going to call Kenny.

Billy's 307 uses a 1.437" throttle bore carb like a 283; the 75 262 uses a 1.686" throttle bore carb like a 305/350. The 72 307 is rated at 171; the 75 262 is rated at 165.
