It's a BLP body and annulars I designed and have made. The vacuum secondary pod is for looks, it's a double pumper.

I would recommend Woodruff Carburetor Specialist for a period correct looking carburetor that is live engine tested and may cost less than a BLP kit.

Correct me if I'm wrong but I believe the holley 950 is a 1 3/8" venturi (750) with a 1 3/4" baseplate. I have read the 950 flow test was at 28" instead of the normal 20.4"water making it inflated advertising numbers. Can anyone comment on this. Not saying it's not a good carb though

sorry the HP 950 Classic is list number 0-80496-1. I am assuming I will be going with a 850 or 950 BLP unassembled kit. Is the 950 the same as holley's 950 with the 750 body and 850 baseplate?

Would you go BLP unassembled vs a New HP Classic? What is the deal with Hp950s do they flow 950cfm? Do they flow less than 850s? Is the BLP 950cfm billet kit different than a HP950, the specs appear very similar for the 850 and 950.

Now that I looked at the BLP BLP BX4 BILLET BUILDER KITS you can have them install the boosters. Still not sure which way to go.

Build or Buy Holley for Big Block Street engine

2021-08-02T15:37:50+01:00

I am slowly piecing a 520 big block together for my ice cream cruising chevelle. The plan is for a mildish build that will run for idle to 5500+/-. Because I want it to look stock under the hood I am sticking with a 4150. I have been looking at BLP unassembled kits and I have been looking at a new HP 950 Classic from Holley. I prefer the gold holley look.
I was told previously the new holley carbs have problems, is this still true?
I have never started from scratch with a carb so installing boosters in a 4150 etc is a bit daunting (can I have BLP install them for me?).

I did convert a 750 dominator to 1050 with a booster change and it runs very good so I am just a little ham fisted.

Thanks for any help you guys can give me.

John
