    Will my stock 350 radiator work with a mild 383 or do I need to step it up?
    If I need to step up, how do I go about getting one that will cool right and fit right in my 90?
    I E-mailed radiator.com. No response yet!

    Just make sure your radiator is in good shape and you'll be fine. I'm using the stock '75 radiator to cool my TPI 383. I had it rodded and boiled several years ago to make sure it was working at top efficiency.

    Can you explain rodded and boiled?

    They take a side tank off of the radiator and immerse the whole radiator in a caustic solution. Then they force rods through every cross tube. The rod is shaped to just barely fit through the tube, so it forces any residue out. Then they immerse it again and power flush it.

    These days many radiators are cheap enough new to make it impractical to try to revive an old one. You're looking at $80-100 to have one rodded while BlazzinOR just got a brand spankin' new one for around $140, delivered to his door!

    Yep, I run a 4 core that was stock in my '79 (with a 400 engine). Radiator.com is incredible. Great prices delivered to your door the next day. Not sure what your truck has, as you said it is 'stock' but that could be 3 or 4 core. Seems you could run a 4 core easily with the proper mounts. Think BigBurb knows the part numbers for the conversion.

    I would recomend 4core. I had a 3core and it just couldn't keep my mild 350 totaly cool in the HOT summer trail rides. I tried everything from mutipul fans to dif. water pumps and thermos and the thing that was the cure all was more water/collant, going to a 4core is your best bet to make sure that totaly sweet 383 build up will not over heat. Of corse you could spend 600 bucks and get an aluminum rad. but the first rock that tears into that bad boy is sure to piss you off....[​IMG]
    I too whent thru raditor.com and had my rad that next day!!

    Where did you 383 owners get your 383? I'm debating on getting on vs having mine rebuilt as a 383.

    Im building mine. You can get a 383 from Scoggin dickeys, supposedly pace parts, speed-o-motive and one other place but cant think of the name.

    Mine came from Racing Head Service in Memphis. They were owned by Competition Cams. They went under after GM and Ford started selling new crate motors so cheap. [​IMG] Any decent automotive machine shop can build you a 383. These days you can even buy brand new crankshafts for them. (Mine has a 400 crank that was machined down to fit the 350 bearing journals). There are complete 383 kits available that inlcude the crank, rods, and pistons. Check out www.jegs.com. They sell the kits. They're even available now for the later one-piece rear main seal engines. [​IMG]
