When they fall into the 30 grand range:D

Your Pro Mod/Top sportsman in the avatar?

only 1400+ gold ones were produced according my stat sheet...

No. It belongs to a friend of mine. Andy Jensen, of Jensen Engine Technologies.

He (actually his turbo combination) was recently tossed out of pro mod when he set the 1/8 mile recored at something like 3.96.

I hope you really don't believe what you just said? If you understand fuel delivery in any way you would understand how unbelievable that statement was.

Let's see....carb rebuild by me about 30 bucks:D New fuel injectors $250 is on the lower side and it will take all day...now lets talk about the computer.:willy: I have delt with fuel injection one other time and I hate it :( It's a huge pain in the a$$... If fuel injection is so easy why is it that Harold Martin(The man that has all the patents for EFI at GM) can't make it work on his racecar?

I swapped out my EFI setup for a Holley 750 & Performer intake, and the RPMs pick up a lot better, especially 3k-5500, but because it's not an RPM intake it falls off after 5800. Don't know what your gears are, but I have 700-R4 w/3.07s and torque is plentiful all over the powerband. I'm considering a port match & portwork on the intake this year.

The main difference between the EFI and carb is drivability - it starts rough until it warms up, may be in part for the cam, but I know most carbs have trouble in the cold. I lost about 6MPG on average, down to 14 in city and 17-18 on highway. It really depends on how many RPMs you're hitting, I cruise around at over 2500 in the city so that may be why it's so low for me. :P

If you don't like EFI, and you like tinkering with carbs, I'd go for it if you're sure that's what you want. I haven't had any problems since the swap last year, and parts for the whole setup were ~$500. It's a lot cheaper to maintain a carb than all those damn sensors with the fuel injection..

I like my tpi. :cool:

Your cruise rpm at 70 mph should be approx 2000 rpm. Did you get your lock up converter wired properly?
If not your trans will be running 20 degrees or more hotter at cruise speeds.

I carbed my 84 for a couple of years and went back to fuel injection (superam). Car ran well with a Holley double pumper. Main problem was fuel perculation after shutdown. The hood seals so well that after shutdown, the engine compartment was so hot that fuel would perculate out of the carb into the venturis. I had to cut these ducts in the hood to allow for engine cooling.

If the carb is easier for you and more affordable, then that is the way should definately go. Sorry to hear that he can't make the fuel injection work. I can tell you that I have raced a fuel injection C4 for years and along with many others, have seemed to make it work just fine.

I had the same issue on mine so I had to remove the hood seal to let the heat out.

I can't even get the back bolt on the drivers side bottom of the runner out:( I have tried swivels, extensions and I don't see how to get at it without removing the wipermotor. I by no way am saying one is better than the other and would like to make the TPI work but :willy:

I'm not down the street, but I am local as you can see. If there is anything that I can offer, let me know.

Use a ball socket 6mm allen on a 1/4"" 6mm socket. I cut one and made my own.

6mm allen will work on a 40 torx bit?:o

Did any of you have carb/air cleaner to hood clearance issues?

You have a PM
