Anyone had any experience with a 950 HP Holley on a 351 cleveland or similar engine? Just mulling around possibilities of a new carb to replace my 780 vac secondary, and thinking either a 830 or 950 HP. Holley recommends a 950, what do ya'll think??

Thanks for any help, great site!!

950 CFM I would think is overkill. At 6000 RPM's, the most that I 351 could take is around 650 CFM. Is there some advantage to haveing an overkill carb?
Thanks
Matt

I say go for it. I have the 950HP on my 383W. Works great. The 950HP is just named that. They really don't flow that much. More on order of 820-830 cfm. The 950HP is just a 750 main body on an 850 base plate. The smaller venturi lets them work on a smaller engine.

I have never seen anyone that had one and didn't like it.

Later,

If your Cleveland is a 4V engine built for big power ... the 950cfm may not be "Over Kill" at all.

These heads are made to breath and breath they do.

I'm running 850cfm and I can tell you for sure ... I'm not over carbed.

I went from a 750 DP to a 950 HP on my 351C race motor, it went from running 7.30's in the 1/8 to high 6.90's with no other changes. The mph picked up and the 60' times got better. It was one of the best "bang-for-the-buck" items I have bought in a long time.

I also had a very mild 351C, 4v heads, hydro cam, 9-1 compression, it also picked up when the 950 was bolted on, and it was only shifted at 6000 rpm. I tird it on a 12-1 compression 2v headed C. It picked up but not quite as much as the 4v headed motors did( 11.30's with a 750 to 11 oh's with the 950 {same day, back to back passes})

Thanks for all the advice, I think I'll go for the 950 HP. It's on a warmed over cleveland, .030 over, balanced, Strip Dominator, Cam Research solid cam, running flattops with 61cc quench heads, rpm range 3500-7000. This is a very informative site, love all the stuff on clevelands and c-4's, I've done the c-4 mods years ago, and they work great. Only thing I need now is a PA servo cover, and a 950 HP and racing I go! ;D

Thanks again!!
