Performance
Have you thought about a turbo Regal 3.8 engine? Lighter and awesome performance. Tons of HP parts. You can get a high RPM engine just by installing a 283 crank in a 350 block. Receipe for a 327. Remember everything is a trade off. Torque is king if your drivetrain can stand it...
Hello,
400 small block bored 60 over! Run away fast and don't look back. The absolute maximum overbore on any factory block 400 Chevy is 30. Twist it to 5K and the paper thin walls will split wide open. PERIOD! That's why your friend still has it. End of discussion.
No easy way out
Hello,
I was GM certified on the C5 as a Service Manager. Bypassing the heater core is something that can buy you some time. The heater core can be replaced before fall. The BCM (body control module) can be sent off for repair at Auto Zone. They had the ability to do just that...

If all else fails!
My budy and I just finished a '69 conv. tri power, 4 speed, red w/blk. top and interior for our collector friend. It had a cat inside when the rollback dropped it off from Ohio. The previous owner spent $30 on brass fittings and rubber hose we replaced with perfect hard...
Transmissiom
Find a TH200 4R from any OD G body like Cutlass, Monte, Regal, Gran Prix, El Camino or many B bodies like Caprice, etc. Buy a master rebuild kit from B & M (red Alto clutches and Koleen steels), a Beast sun/reaction shell, TCI clutch apply piston assemblies, an B & M Super Cooler...
Better idea!
Does you '81 still have the old TH350? Call Art Carr and get a TH200 4R. You can use the same trans. mount, cross member location, and driveshaft as the TH350. The 200 can shift into OD at wide open throttle (WOT) which the TH700 R4 never will. Art says the...
Size
EFI or carb. size matters. Carb. much more so. Performance carb. 650 (Holly), 670 (Edelbrock), and 700 ish for EFI as it self learns. Still EFI can't overcome poorly mismatched components and too big is still too big. Agressive cams are always deal breakers. Call the manufacturers for...
Drivabilty, response, fuel economy, no adjustments for humidity, BARO, altitude, temperature, etc. Carbs are WAY more complicated than any EFI system. Spent years as a carb man on a winning drag team. Be smart and sure that it'll start (heat soak) and go EFI. Used the HO one one of my projects...
Your intended usage will be the major player in the right direction for you. Street, solo, sound, drivability, or some combination. Good rule of thumb is $300 = 30 hp exhaust or 3 hp intake. Does your state allow removal of the emission equipment? If so then the answer just got a little easier...
Check the voltage at the blower. High gets full battery voltage while lower fan speeds have reduced voltage. Check your manual for the exact readings you should get. If the voltage regulator is bad you will only have high speed. Look for high resistance in the motor itself provided you are...
All have given good advise. Do you have a firm pedal? In what order did you bleed the brakes? Is the paking brake truely releasing? Look under the vehicle to make sure cables are moving freely and not just the release handle. Sounds simple, but it always is. If the brake proportioning valve is...
