Post Stipud ? Maybe/Need help determining my Carb and intake

Okay I'm new to this forum so if i'm in the wrong section let me know. Well I just turned 19. I've owne alot of import 4 cylinders but I've always loved 60's-mid70's muscle cars. First of all I don't have one yet because they are valued so high today I want something not in the best shape doesn't have to run I want to rebuild the engine and restore the int/ext. myself. Anyway what this post is for:

I bought an 88 suburban. I ripped the computer out and injectors. I put what I think is a stock intake manifold off of an early 80's 350 engine, i put 650 cfm double pumper holley 4bbl on it. Now my much older cousin who has lots of muscle cars and currently owns a 1970 ford torino with 460 and C6 transmission with the same carb. He said the carb is to big for my stock intake. Now if anyone could tell me what a good carb. for my 350 stock intake would be either 2bbl or 4bbl I don't really care right now 2bbl. would be nice to save some gas since i didn't buy this for power I bought it to perform the injector to carb. swap. Also to become familiar with the older motors for when I get my own muscle car. Any help would be greatly appreciative. Also could anyone tell me if 69 350 cast iron heads will fit my 87 350 I have a set but they look to be too tall and my valve covers do not fit from my original heads. Please help. Thanks

Robert

The 650 carb isn't too big for the 350, are you sure it's a double pumper? As far as doing away with the injection, why? Sounds like a step backward. Dan

Backwards indeed

Well originally this was a project for me to experiment with the old intakes,carbs and the entire engine. When I bought the suburban I had a 4 cylinder to drive got close to 30 mpg. Then the timing belt slipped a few teeth and beleive it or not ripped the head off and bent all 16 valves. So stuck driving my gas hog.

Yes i know it's not to big for the engine, I was told it was to big for my stock intake and that wouldn't idle right with all that fuel. I'm positive it's a 650 holley 4 bbl. the double pumper I'm pretty sure of it has these 2 springs one on front and one on back when you push then down the front sparys fuel in front and rear sprays fuel into rear. Not sure if that's what double pumper is but my guess. Also need to add another ? I have fuel pressure regulator with gauge i usually have the gauge around 5.5 or 6 any ideas on what to have it set at?

This maybe a little of the subject, but what kind of import did you have?If it is a honda ,it is not that hard to pull the head and replace the bent valves.Carl

If its a stock intake, than you had to have used an adapter plate to install the 650 Holley. as far as it being to big for the stock intake, isnt really the issue. The issue is , is it the RIGHT carb?
The stock intake would be a spread bore (quadrqjet), in my opinion that would be the best carb for the application. they are way more cfm than you NEED , however, due to the spreadbore design, there far more forgiving.
As far as a square flange carb goes....on a stone stock 350 that wont be revved past 5000 RPMs... Id use a 570 Holley vac. sec. John

The Import

My car was a 91 mitsubishi eclipse GSX 2.0LDOHC turbo AWD
I took the head off to discover all 16 bent valves it needs to be rebuilt anyway but i plan to fix it when i have more time. A 4 cyl. isn't my main concern now I want a 60's - mid 70's muscle car with v8. will sell the eclipse for parts though have a few performance parts never been used before for it also.

I understand,nothing like the sound of a v8 is it? That is why I was driving a ford lightning 60 miles one way to work instead of a 4 banger.And was working on honda,s.
On the honda,s we would just replace the bent valves,and timing belt.That is why I thought I would ask.I thought it might be cheaper for you to repair your import.But if you want a something different I understand.Carl
