[DeTomaso] Current Recommendations on Carbs

[Will Kooiman]

Lots of people recommend Larry Stock, so you can't go wrong there.

I am very happy with my Holley Ultra HP 750.  This is not the old die cast 750 DP.  It's like engine porn - all aluminum, very smooth operation, billet metering blocks, dominator fuel bowls, etc.  It doesn't have ported vacuum, though, so if you run a vacuum advance distributor, this is not the carb for you.

If you need ported vacuum, try a Holley Street HP 750.  It has ported vacuum, but no choke horn - which is only required for wimps anyway.

I second Perry’s recommendation. I ran one of Larry’s 700 double pumper carbs on my Pantera for years, then had it punched out by his supplier to 750 when my motor grew to 408 inches. I got another one of Larry’s 700 DP carbs for my ‘66 Shelby GT350 clone (with a 331 stroker) and it works fantastic there too. 


Tuned properly, a double pumper is just as economical as a vacuum secondary carb. But it’s so much more responsive….
