You can build or adapt /modify a 1 5/8 header or a 1 3/4 header. Both will work very well
and be miles ahead of what you got.
Another way to build a effective powerfull header, when room is tight is a 4-2-1 design.
This is not a tri Y design. The 4-2-1 scavenger header w collector acts much like a 4 into 1 long tube w merge collector.
Usually where a block hugger header fits a C3 long tube corvette header will be very close.
center dump tubes.
may only need minor modification. thats nothing for a welder.
If routing he primarys back and down is better look at a 3rd gen camaro header. Or a S-10 header
Or a 2nd gen camaro/chevelle header as a base.
The typical little block hugger headers have very small primary tube diameter. No scavedging effect
poor flow. Often worse than a corvette ram horn exhaust manifold. They are for near stock motors.
Fit easy, cheap, no power. Great for 300hp street rods.
The car is a 72 celica with fabricated tube frame.
You got tons of room to work with.
Its very easy to make up excuses..... No buddy is suggesting a 25K budget.
By the way that simple roots street blower motor can be built complete for well under 5K
Its real simple. and you already have most of the components. The punny carb isn't once of them.
Ita a 330 to 360Hp carb for guys that do not want to go fast.
