    I believe it was junked more than 15 years ago. I bought the engine (and a Buick T400 trans) for $600 from a guy in Romeo, Michigan who restores old Buicks. He had three 455 engines in his garage for decades. He built up one of them and has it in his very nice (showcar) 41 Buick. It is a 3/4 race with hemi-killer cam, etc. I took a couple of pictures of his 41 Buick with the 455 engine in it at the time and have attached them below. He has three other Buicks from 55 to 64 in various stages of restoration. I also bought my 455 shorty headers from him ... he has three big garages and a lot of Buick stuff!

    I had to go with a circle track pump and a remote reservoir. If you want to play around with a pump from a 4th gen Camaro you may be able to do a junk yard conversion. There will be a lot of work with this pump to make it work. I think most just went without power steering.

    Here are a few sources

    Let me know if you want more info on how I did it, will be glad to help.

    Good to see things are alive and well. Lots of stuff discussed here is in my original tread around my Procharger build way back in the day :) .

    I'm curious who is running one of the street hydro Roller Cam's with boost if anyone and how you like them?

    After 8.5 years of running 12PSI my block finally cracked in the #8 Cylinder.... New stock block is being prepped for all my stuff now, just up in the air around what Cam I should run this time around....

    Switch to a Buick 350 and enjoy some reliability under boost!

    There are a few considerations that will help determine the cam specs.

    Do you still have to pass emissions?

    Are you going to do a block girdle instead of the Halo?

    Are you going to use an aftermarket rod?

    Intake Manifold?

    In any case the next cam should have a 114 degree LSA

    I went with a solid flat tappet custom from Scott Brown. All I can say right now is it idols nice (for it's size). Will know more about performance when I get the refreshed trans and new converter in. Hard to tell how hard it runs when all the clutches in the tranny are gone (have no idea how that happened)! Everyone says a solid is noisey but we can't hear that stuff over the blower whine anyway.:Brow:

    I read all of your stuff to help me with my project. Good to hear from you.

    Work in progress, i started fitting the intercooler tubing and hoses, need to cut the radiator support to gain access to the intercooler in and outlet....

    I also went with Scott Brown Cam but with hydraulic lifters. But it will no go into this 350 (it's a mule), i have another 350 to place into the Buick when it will be fully restored.

    I am doing the same thing.. Beating on a stock 350 before I swap in the good one...

    Looks like you are doing the intercooler the same way I did. I had to cut the core support also. Will take a picture this week to show how it was done on mine.

    8 years of beating on the 462 with 11 to 13 PSI wasn't reliable? I'd call that pretty dang good....

    Ahhhh you did your homework :) Sticking with the Halo, but doing a 1/2 block fill on this one.

    Rods will be stock with ARP's, I don't spin past 6k

    Emissions isn't an issue this year (law's changed), in the past they did.

    Manifold is the SPX.

    I'll run a 113 to 114 LSA for sure. with a smaller lift like 510ish in and 520 ex is what I'm thinking. My past cam was on that I picked for non blown application but just ran it anyway the entire time.

    Any of you guys running a default TA roller grind?

    ---------- Post added at 04:07 PM ---------- Previous post was at 04:04 PM ----------

    I ran mine like that for a while as well, but when I went to the F series, I took that first 180 degree bend out of the picture, ran straight across, the routed in front of the radiator for the intercooler. I picked up just about 1lb of boost by taking that first 180 out.

    Which Crower cam where you using?

  13. Nitro71455

    Nitro71455 Procharged 455 boost baby

    Off the top (and it's been a while) I think it was:

    112 LSA Intake 228 .511 EX 230 .511

    The cam came cut much shorter on lift that it was advertised by Crower.

    I just ordered a New TA Hydro Roller setup. Ordered the following grind:

    113 LSA Intake 232 .535 EX 238 .540

    Not a huge diff, but a better blower cam than the one I picked before the blower was even a brain thought back in 1999.

    So far the flat-tappet TA cam I had in the last engine (TA310) ran as well as the Crower roller cam I have now.

    It has more duration (280) and more lift (.645)

    I am thinking the blower likes 110 degrese LSA with about 230 degrese duration and about .510 lift.

    What is everyone elses cam spec ? Tell unless they are not top secret?

    Anyone running a roller version of a TA 310?

    JESUPERCAT No Slow Boat

    Micheal here is the card for our cam in the 6/71 blown 425. With our rockers we are at about .610 lift at the valve.

    I was running a TA 413. New cam is a flat tappet solid lifter that I am thinking is too big.
    Was going to check on if I degreed it correctly this spring but broke my leg and put everything behind schedule.
    LSA 114*
    Intake at .050 is 244 lift is .535
    Exhaust at .050 is 260 lift is .545

    I have ported iron heads no flow numbers.

    Here is a grind that has been suggested to me. Another solid lifter cam.
    LSA 114
    INTAKE @ .O50 234* .544 LIFT
    EXHAUST@ .050 242* .544 LIFT
    OVERLAP 10*

  17. I now own this engine and it is going in my 67 special but with a procharger d1sc instead of the Vortec Jim was running. looking to tame it down to 700-800 streetable hp and keep the car looking stock on the exterior

    My question is how are you going to cool the engine when there is a tall fill of the water jackets?

    I only did a half-fill for water flow since mine is a "street" car.
  19. The new style TA timing cover has provisions for external hoses off the water pump outlets. I have 2 -10 AN hoses running from water pump to fittings in the rear of the intake that feed the cylinder heads. Jim W said this is plenty to keep the heads and engine cool enough and i will run an oil cooler. The SRE aluminum oil pan will help considerably as well.

    It will keeps things cool except for sitting in traffic. Your oil temperture will raise fast.

    I also have an aluminum SRE oil pan and mine has a temperture Guage. Get one.

    What intake do you have that you can tap and thread the rear corners?
