L98 TPI to Carb
Who has switched over from TPI to a Carb and did it make a difference?
Were you able to pick up RPM's with the switch, I know I will lose mpg's but I put less than 500 miles on my vette last year. I also am not picking up on the fuel injection.:willy: Just looking for some input :cheers: |

Lets face it the C4 is not cutting edge technology, its main appeal is its roadster like ride qualities. I grew up driving carbed cars, and that is what I like, same thing with a manual transmission. If you want to be chauffeured around by a robot, go ahead, but don't cry when the machines take over and you can't do anything for yourself.

Still using your 8 track? |
If you carb it, you should get higher rpms just like the 350s of old. The TPI is whats holding the L98 from achieving that (along with a restrictive exhaust). Im not sure what the horsepower increase will be with a carb on the L98, but there is a engine Im thinking about getting called the ZZ4 that is rated at 355hp with a carb,but with the tpi that I have now will only be about 265hp, so you can see there is a great difference in hp between TPI and carb. Higher power can be achievied with TPI but the cost is much greater.I personally won"t go to carb, because thats not how the car was built originally,but if power is what you want, it can be gotten cheaper and easier with a carb..WW

Switching to a carb is not cheap,Intake,carb,air cleaner,FPR,Dizzy,TV cable bracket :cheers:

I agree that a better intake manifold would increase both the engine operating speed as well as some of the usable horsepower, but for the sacrifice of the lower end torque. Trying a larger throttlebody and a les restrictive manifold might surprise you. There are numerous articles that you can find on the Web that show improvements in h.p. by increaseing the intake flow and decreasing the exhaust back pressure. |

Maybe a dumb question, but why would the distributor need switched out? |

I guess I would question what issues you have with the fuel injection? And what you mean by more r.p.m. There will be issues with hood clearance to the carb given that the car was not designed to have a carb sitting on the top of the engine. Not saying it can be done, just curious why?

you're starting w/the wrong Vette.......should have bought an older model equipped w/a carb. if that's what you like.....

Be very careful with the transmission TV cable. Carb swaps require dedicated, specific brackets, and careful TV linkage tweakings to allow the trans to remain alive. If the tv is wrong, trans will eat itself up quickly.

This one basically fell in my lap....I took it in as a trade on a snowmobile....But if it was a case of buying what I really wanted, it would have been a split window big block.
I understand; maybe sell it and buy something else? |

So when are you buying the 63?:lol: |

Thanks for the tip....I work in a prototype shop, so I think if I switch over the brackets and cables will be hand made...we did all the prototype cables for the Dodge Challengers.
Not a big deal to get them set up properly, but overlooked often. If I can help, let me know. |
