I am trying to get the 77 Sprint making noise, but could use some help on 2 remaining challenges.

1) Need to convert to a high pressure fuel system to supply an 84 TPI system off a Camaro. Fuel cell in bed best idea?

2) Need some custom made headers. I have a set of spread port Brodix heads with angle plugs and they have created me some real headaches. I have cobbled together a set but they are not worth much more than a set of prototypes for the real thing.

All ideas appreciated.

Bob.

What are the goals for the engine? The heads seem serious for the TPI system with out major modification. As far as the tank you can have your stock one modified to accept the proper size lines or there are some aftermarket tanks available for EFI. Please get back to me on some specs.

As far as the headers I think you are on the right track, unless a set of block huggers would work. if you have some pics would be great.

Bill,

Thanks for the reply. My dream was someone would tell me "Charlie's Mini-Mart and Body Shop" is the best place to buy a drop in high-pressure in-tank pump unit and "George's Meat Locker and Welding Shop" would build you a set of perfect, coated headers using your prototypes in a few weeks. But reality sets in and I am looking at options like a fuel tank in the bed so I do not have the a pump sucking up out of the gas tank. Maybe a booster pump near the tank to feed a primary 60 psig pump and some 6 or 8 AN lines, like you discussed.

As for the heads, you are very correct. I simply did not include all the details. The bottom end is all new, a cast steel crank, 6" rods with premium bolts, forged Probe pistons (~9.8/1 compression), main studs, 1.6 ratio steel roller rockers, etc. The cam is not stock (~210 duration at .050), nor is the TPI chip.

This is to be my street driver, bottom end torque (<5K rpm) is the primary goal. I know the TPI will limit air flow to ~650 SCFM; maybe the future will bring larger runners and an aftermarket intake manifold. I have placed a performance 700R4 behind the 388 (383 + .060) with a "one step higher than factory" stall torque converter and foresee a set of 3.73 gears replacing the stock 2.56 rearend gears along with a set of rear disc brakes.

Right now, its finish the TPI and exhaust to get it running. Then rearend gear changeout to make it more drivable, followed by brakes to stop quickly. Once those bugs are refined, its body and interior time. All being sensitive to the budget as the kids have to eat also; that's why its a multi-year project.

I drove a '74 El Camino Classic just out of high school and want something similar with around 400HP to drive now.

Thanks for your response.

PS, the heads are some of the "smaller" Brodix heads ("-8" heads with 194 cc intake runners). I should have just forked out the dollars at once and bought something more "typical" rather than the "deal" I got on these. Could have avoided the header challenges and the extra water routing problems (center head cooling ports).

Fuel tank solution: grab a plastic tank and straps out of the last of the RWD Caprices. They fit well with a few added brackets for the straps and are already set up with the in tank pump and everything needed for EFI. The only issue you may run into is that it is setup for a rear filler neck while you need a side neck on the Sprint.

My vote goes to a "fuel pump module" for the EFI conversion. Check out the pumps used in '99 Ford F250/350/450 pickups. Should have a moderately capable pump and bolts into the top of the tank rather than use a lock ring. You will have to mess around with the fuel gauge sender but that is not hard either (can run a 2-5k ohm correction resistor in parallel with Ford sensor).
