I'm just looking for reliability and better operation, not big numbers. It had a cam swap done idk how long ago, it was solely used for towing a tandem axel 20ft travel trailer, had a camper shell on the bed its whole life, no bed usage at all.I have ran many 2 barrel engines that were ridiculous in the power department.
I had one friend with his 1987 chevy truck that had a 2 barrel on it get a 4v intake off of me a Q jet iron intake and then he topped it with a Q jet carb.
Zero power gains anywhere.
If you do get an intake look for a Mopar 360 cast iron 4 barrel intake or a 340 4 barrel intake.
DO NOT get an edelbrock performer intake.
You will not make the power with it that the Mopar intake will make.
Here is one read you may really like.
Study it and notice at the bottom the test #2 was with Thermoquad and stock 4V intake.
These fools spent bad money on that edelbrock intake and a Q jet carb and lost power.
Only thing that made power come way up was a cam change.
They would have been more power ahead with the stock cam and porting of the heads.
I have done the cam swap on stock heads deal and it never panned out. always lost low end TQ and gained HP in the last 500 rpm of the curve.
When I began porting heads things came alive.

My quickest 2 barrel engine was a 1970 Buick 350 and it had a stupid cam in it would not idle under 1200rpm.
3500 stall converter and I put it in a 72 Nova.
115 lbs lighter than the SBC and I had gutted that car to reduce weight.
I put wrinkle wall drag slicks on it and had them on for 1 launch in front of mother-in-laws house.
Just about hit the rear bumper on the pavement. Broke the rear shock mounts off.
I did not run slicks for 15 years after that.
I would shift that engine at 7200 rpm with the GM 2 barrel and with an adapter plate for a 4 barrel and a Mopar AFB 750
It would go 7600rpm and kept pulling I got scared it would blow up and I shifted it.
Those old rods were cast and I am surprised they never failed.
I will keep my eyes peeled for a Mopar iron 4 barrel intake.
Here is another read and this guy swapped a factory 4v intake for the Air Gap Edelbrock RPM.
Not much gained there either.
Modifying And Testing A Dodge 360-Cube LA Small-Block On The Dyno
I have ran that Air gap on a SBC and it may make more HP on a dyno but driving around in our state it was terrible.
I had to add a lot of fuel to the carb to make it work.
2 friends with different engines had the same issue.
Lots of stumbling and dead spot when you get in it.
More pump shot and quicker fuel curve with as much as 10 thousandths more jet on all 4 corners.
Just horrible.
I put the regular RPM Non air gap back on and things smoothed right out no more stumbling and I pulled a bunch of jet out.
MPG came way up.
Good luck.
