Thats for my 275 drag radial car im building. It is going to have some boost also.

What about the one on the stand in the back?

knuts82

Thats like a 2002 or 03. 4.8 that was in this truck. Ive got a 13:1 380in solid roller sbc hiding in here too.

Do you remember where you got the motor mount plates from?

knuts82

I found them on ebay. They are adjustable 1" forward or back from stock.

Hey man im about to put a 5.3 in my 86swb and put ebay tutbos on it have you had any problems out of yours? And so is your block a 4.8 bored out or a 5.3 bored out?

ls86swb

And did you make all your piping your self or was part of a ebay kit that came with the turbos

knuts82

The turbos are CX racing brand and have been perfect no problems at all.. This motor started as a 4.8 but the 5.3 and 4.8 blocks are the same.

The last one of those dual fuel pumps lasted 38 miles. Both pumps failed and we had to trailer the car back to the shop. Not going to use any of those again at any price.

So the bore on the blocks are the same just different cranks? Sorry if these are stupid question im just learning about the ls motors. I was thinking about boring my block out to run the same size pistons as the 5.7 would this work or would the cylinder walls be to thin for boost ? And what cam do you have in it ? Cuz I read on here the you got a 3400 stall and u said u were blowing through your stall

knuts82

Ive ran three of the Dominator pumps with race fuel, methonal and E85 and never had a problem.

knuts82

I built everything myself.

knuts82

Yeah 4.8 and 5.3 have the same bore. 4.8 has a shorter stroke and longer rods same pistons. Lots of companies over bore 4.8/5.3 blocks to build Iron ls1's and the cam is a 287XER comp. The converter is a Billet Revmax built for this setup it works great at 16psi but over 23 thats a different story.

Ok cool. Is that a super victor or victor jr. Your running? Im wanting to run the super victor with a four borrel throttle body with 243 heads. I found a god speed turbo kit.

Did you go with the T3 or T4 hot side? Is there much lag (open for interpretation, but still worth asking) having twin 61's on a relatively small displacement? Any details on the FMIC and how it performs? Great build. Keep the pics coming.

knuts82

Thanks..
They are T4 .68ar 62mm turbine. As far as lag... The cam im running has alot to do with it but i have full boost by 4500rpm. Boost with a setup like this is like hitting a light switch its not really their but when it hits then you better hold on cause it instantly goes to whatever im set at be it 16psi or 23psi ect. As far as the intercooler it has two 2.5" inlets and a 3" outlet. I dont log temps but it seems to do a good job.

Here are the turbos.

Any updates on this project?

knuts82

Just in the process of changing to 3:42 gears and new axles its still to cold out around here to drive it. Put about 400 miles on it last year..

knuts82

Had to do a little straightening of the rear housing before welding..
Now its ready for some gears..




Also welded up the trailing arms and put in new Poly bushings.

knuts82

Well I finished and installed the rear a month ago. Took the old girl out for a test drive, well a mile from the shop shot a rod out the bottom.. Put in a new motor I built for my drag car since its not ready yet, belt flew off in traffic overheated it and torched #7 piston. Motor hit 300 deg. Having some crappy luck this spring I guess.. lol





On a brighter note I had a Harley sitting around so I chopped it up and painted it to match the C10.
