Just bear in mind a BB will have its way on your drivetrain (i.e axles, not just the tranny). The front will probably sag a little due to increased weight. You want a BB radiator too, which may be smashed in the wrecked donor vehicle/wwwthreads_images/icons/crazy.gif

I was just wondering where youve been. I think my drive train can hanlde it the front might sag just a tad but I think a few cranks on the torsion bars shold fix that, the 14 bolt semi floating rear should be fine? my trucks also had the rad swapped out before by the prefius owner and it seems alot bigger than ones if seen on half tons, could be my eyes though. the heavy dut 4 speed shold be fine to I think.

14b SF should be cool. I think that´s what 454SS pick-ups have, and those rock!/wwwthreads_images/icons/laugh.gif. Can´t remember what exhaust you have, I know you replaced some bits & pieces a couple of months ago. It might be too small? Another thing, the fuelpump! I dunno if BB and SB pumps are different? Oh well...It´ll probably work out okay, just take your time.

Grab the torsion bars from the 3/4 or 1 ton truck. They will solve any problems you have with the front end sagging. You might also want to just grab the whole computer out of the other truck. I'm told the 350-454 TBI swap isn't to hard, if you grab as much of the powertrain and computer stuff as possible.

Hmmmmm.......454 TBI with SM465......hello 8mpg! Might want to try and find a 3/4 or 1 ton with the 454 AND a 5 speed stick, that'd be a NV4500 if I'm not mistaken. All the beef of your SM465, but an extra OD gear to actually get you some gas mileage.

Andreas,
Ive finally redone the entire exhaust from the manifold crossover back, I now have a high flow cat with a cherry bomb muffler wich I dont like, and the entire system constists of 3" mandrel bent pipe, exiting at a 45 behind the right rear tire. Should be fine with a big block I hope.

AJM,
With the 350 Ive got as high as 18mpg cruiesing down the interstate, I think Id have a problem with not haveing the over drive if it werent for my tires. Im sure if I had stock 225s shesd definatly be belowing down the road,

I priced a complet motor yesterday and the wanted 1800, and didnt realy say what they meant by complete motor, maybe ounce you buy the thing the rest is pretty much yours, so hopefulley the wouldnt put up to much of a fight letting the computer go.
I better go finish my body lift, talk to everyone later

I guess a 3" pipe will be fine as long as you stay with a stock 454. BUT, consider building a TBi 383 or a 406 before you start buying things. I´ll help you to the best of my knowledge. A TBi 383 with some decent parts will outperform a stock 454. Just for the fun of it I built a TBi 383 in Desktop Dyno. A mild rollercam (Xtreme 4x4 258 Hydraulic Roller), 9.1 compression, some porting, good headers and a 500 cfm carb should give you upwards 450 ft.lbs (flywheel) from idle to 4500rpm. That´ll break some u-joints /wwwthreads_images/icons/laugh.gif A 406 with the same parts and a bigger carb (650 cfm, i.e BB TBi throttlebody) will push out 490 ft.lbs. Problem is a lot of work and waiting for parts. You got a kichentable ??/wwwthreads_images/icons/laugh.gif/wwwthreads_images/icons/crazy.gif

On the other hand, a 454 with some decent parts will kill everything/wwwthreads_images/icons/laugh.gif

Ive thought about a 383, but for the reasons you talked about I dont think Id want to do it, all the down time, unless I founda block to build on till everything was, I was gona get shorts old block and buil it but she pulled it out from under my nose, darn her.
but I dont think 1800s tobad for a complete motor, with way less miles than mine, through some headers, intake and maybe a TBI spacer, still not cinvinced with them yet. and upgrade to an MSD ingnition. and it should run pretty decent.
these would all be gradual steps as the money comes in. Id want all my upgrades to help out the tourqe so maybe the headers shouldnt be on the list, but I guess ill have to see waht happens.
anyways thanks for the info and ideas
Evan

I want a big block soooooon, oh and the kitchen tables not equipped yet for that line of work.
