How well will TPI run compaired to LT1 setup? I have never done anything but drive a TPI car that was stock, how hard is it to get a custom burn setup for tuning thru a lap top? Is there afordable setups?

imo, most affordable to tune, and use conventional crab type dist. like stock 95-99vortec

Well, i might go back LT1 if it seems to hard to have a distributor in the back, what is the minimum mileage of a used LT1 you guys would recommend for installing a hot cam. I will definitely go with a bit more ***** in the valve train area while i am in the process.

Was the head swap due to gaskets pissing into the oil? Coolant in oil does a nasty number on bearings.

Dont know if you have your mind set yet or not, but putting the dist. in the back with a gen 1 motor is real easy!! And its really cheap to make them fast!! My first go around with a mild 383 was a mid 7 sec. car in the 1/8th!! Of course the fogger kit ended that for me so now im tryin to really have some fun!! Ha!

removed and reinstalled,, and tha causes
the spun bearings and locked engines, happen to me once, they dont all do that but it does.

I have done 7.5 with a heads/cam Caprice. The shift points were 6100rpms so it is not wild by any means.

Here is the part # for the DFI LT1 injection system, #77022L. You will have to scroll down on the provided link until you get to page 6. http://www.accel-dfi.com/pdf/DFI_07.pdf
Yup thats it!! Really there all the same system with just some minor differences!! Like I got a lsx system and am using it as old school!! Just had to not use the lsx coil harness and got a different dist. harness!! But the main computer and harness are all the same!! (Basically you can buy any used system from anyone ie ford or chevy and get your harnesses) 
But im not saying to do that!! I would check with one of our great sponsors!!! They can get you everything you need!! And its Veeeeeery user friendly!!!

Ok, so, i am looking into a megasquirt system possibly, i hear they are cheap, i need to slow down, i am sure i will need a lap top computer. I am learning so much about EFI and tuning and even the DIS setup my head is spinning, i am glad i am not in a rush. Ok, so how hard will it be to tune the megasquirt setups? I am verry interested in it. I think it will work, but i dont know if i wanna intergrate a TBI distributor because i have one laying around or if i wanna use some kind of crank trigger. What you guys think?

Found a MS system for 250ish on ebay and laptops for 200$. So the way things look i might go this way. Anyone here tune one of these/have experience with it?
