Do you guys have any thoughts on intake manifolds for a setup like mine? I hear alot of guys running Edelbrock intakes. My Brodix HV is basically untouched so Im wondering if I should have it worked on or buy something different.

intake
 
I would clean some of the casting up and gasket match and use the intake you have.

damn...probably spent 1100 bucks and picked up half a tenth. :?

Here's my 2 cents. The 1250 is probably a LITTLE to big, but since you already have it it's free. Right? It might actually run a little quicker and faster with a little too big carb, but consistency will suffer. A 1050 would be more consistent. JMO. I'd try the 1250 and see if it does what you want after proper tuning.....

carb
 
Tod74 the carb was just a little over $900 and picked up a half tenth on an already perfectly tuned engine.The car runs 5.30's 1/8 at 2500lbs on gas.The engine is a n/a conventional head 540ci.Just think if he went to alcohol.

How do you pick up a half a tenth of a perfectly tuned motor :?: :lol:
I am on board to get this answer :D :shock:

carb
 
It had a 1050 Quickfuel carb, was perfectly tuned the car ran 5.40s, then switched to the 1200 pro systems carb and after that it ran in the 30s with only a carb swap.I am not trying to sell their carb,this is just the good experiences i have seen with pro systems.

Good tuned 1150 gas carb on 565 sent it to APD to work there magic picked up .15 ... both Pro Systems and APD have there stuff together on gas stuff ...

I may also need a little help, I have a 468 (4.310x4.000) Edelbrock square port heads, 2.25-1.90 valves, 13.3 comp, .722-.722 lunati cam, all in a 3500lbs 66 Chevelle, 400 turbo, 5500ati, and a 5.38 gear....What do I need for carb. I have a 830hp and it ran good on my last 468 but with much less compression?????????? I also run 1/8 mile ONLY (5.38)

Call Pat at Pro-Systems. I bought a new one from him in December for my 540. I won't have my motor on the dyno until April and I can't wait to see the numbers. Good luck! http://www.prosystemsracing.com
