    typical mild buick 350 build:


    aftermarket 750 cfm carb(stay away from BG) or 750/modded 800 q-jet

    1inch to 2 in carb spacer

    stock 4v instake swap or aluminum poston/ta intake(weight savings)

    recurved hei/points distributor

    bigger TA valves,

    optional ported heads/gasket match

    cam choice TA 212, poston 110-114 camshaft

    8.5-9.5 or even 10.1 cr pistons

    poston/ta/hooker headers mated to 2.5 dual exhaust

    typical supporting mods

    3.08-3.73 gears (any gear brand other then richmond)

    tire size ranging from 245-60/295-50 and 275-60 15s on atleast 15x8 rim

    eaton posi

    2400-2800 stall torque converter(coan is a great choice)
    t
    rans-go shift kit part time manual/auto version



    any combination of this should yeild around 200-250 rwhpand 15s to 14.5 in the quarter.

    actual results will very on youre actual specfic combo and the altitude of where youre racing

    I want to add the T/A stage 1 intake and a cam and lifter set up to my stock 350. Do I need any head work or will the stock heads be fine?

    I'm sure you already figured this out but no you don't need head work...just a perfect opportunity if you have the cash..future reference for all that didn't know.

    Picked up a complete 350/350 combo.
    My son wants to do a build on it this winter.
    Its his car, and he wants a monster...something that scares old ladies off the street, and makes women pull their kids back inside the house until he's past...

    Raunchy,...lumpity, lumpity, lumpity cam.
    Blow the tires off with a mash of the go pedal...

    What do we need for a parts list?
    Will the TA SP3 intake with 850 double pumper work ok?
    Just how much compression? 11:1?
    Valve sizes requirements?
    Looking for a 4 core aluminum rad...any idea or links?

    This is his "Look at me" car...only really drives it in town...cruising around...no long trips.

    Thanks in advance.

    11 to 1 will require pump gas. or go 12 to 1 and run e85 if that's available near you. get a custom ground cam from scott brown(buyracingparts.com) or go roller. your going to need to cram the biggest valves you can and port heads to maximum,1.92/1.55 are available. . your going to need proper rear gearing. proper trans setup/convertor size.
    consider a big bore setup. sonic test block for size of pistons. .100 overbore would bump cubes up almost 20 extra.

    Except for one problem... it still blows head gaskets and has not made a good run yet.

    The 11.1 comp should work may need some race gas for a little extra octane. I run 5 gal with 15 gal of 93.

    The SP3 with a Holley will work fine. I like a double pump myself.

    Port the heads out, put in larger valves.

    use a 3000 stall, 373 -411 gears, if you do the 200r4 trans you can go to the 411 gears.

    mine has been reliable for 20+ years

    cam some where in the 230-255 range and 510 lift or more if you like, mine is a 230-245 @50 510 lift 116 lsa Lunati
    Pick the one you like, whether it is a TA cam which no one seems to like for some reason, or a Crower cam which look good Level 4 sounds good, or the Scott Brown cams that a few people like here too.

    I would do the roller cam now eliminate the lifter problems with the old school cams so there it has to be custom.

    You will hear arguments all day long on all of this so do what you feel is best with the information given. Which is usually the case here.

    Thanks for the info guys!
    Will be porting the heads for sure.

    For sure items:

    T/A SP-3 intake
    Holley 750 or 850 double pumper
    T/A headers
    1.92" and 1.55" valves

    Are the roller rocker mod kits still available? (Using the small or big block Chevy rockers)

    Good company for the Pistons/rings? (Anyone use gap-less?)

    We want to get away from the points distributor...should we just order a T/A HEI unit?

    You can get a pertonix or other conversion that uses your distributer or even let points trigger an msd box. Check buyracingparts.com for pistons . they have custom head gaskets also for big bores. Can do custom cams also.

    If we wanna go that route? Is there a problem or issue with installing this type of roller rockers on the sbb?
    We. are very new to the Buick scene, and any info that would save headaches is very much appreciated.

    Had a look at the Crower site.
    The stage 4 sounds like the cam for it, as the transmission we have already has a 22-2500 stall. (May have to upgrade to a 3000 while the engine is out, just to save the bottom end response.)

    If we were to go with a roller cam...any suggestions?

    You do not really have to go with the roller cam it is just better to use it since that available now. The old school cam will be fine you just have to make sure you use the right oil for breaking and running. Brad Penn and Joe Gibbs oil come to mind here. Can be bought at Summit Racing.

    TA sells the roller cams and I am sure you can get one from Crower and I am sure the Scott Brown cams can do it also.

    The Chevy rocker set up did have some problems with the plate coming up out of the head but some people have had success with the system. The person that was making them I think is not making them any more, he had a medical condition that kept him from working.

    The TA roller rockers are expensive but they will last forever.

    For extra cubes look at the eBay nascar take out rods, with the 1.889" rod journal size rods you can add an extra .090" of stroke and with the 1.850" rod jounal size rods you can add an extra .140" more stroke. With around a .060" overbore and an extra .090" more stroke you can be just under 370 CID(368.85 CID actual). With the extra .140" more stroke and .060" overbored you would be at 373 CID.


    Of coarse I would recommend spending the extra around $50 to $100 to have the block sonic tested to see how far you can get away with an overbore. I have seen a sbb 350 block thick enough from a sonic test to be taken out to a 4.00" bore, with a 4.00" bore and the 3.990" stroke you would have a 401 CID sbb!

    Just remember if you commit to the 1.850" rod journal size the crank should be heat treated because they only make the hard bearings for the 1.850" size. With the 1.889" size you can use the soft stock Toyota bearings without having the crank heat treated.

    The AutoTec pistons can be bought with custom wristpin, compression distance, bore diameter sizes for the advertised price if you decide on using the nascar take out rods.

    The nascar take out rods will take anything a sbb can throw at them, Enginecraft has done a few sbf turbo builds with nascar take out rods that made around 1,200 HP, so for the price they can't be beat.

    If you are interested in this route let me know and I can help guide you down this path, even an N/A build would benefit with a set of these rods. GL

    By machining 0.050" to 0.070" off the heads, doesn't that screw up the intake manifold alignment?
    how much per side do you have to cut off the intake flanges?

    Edit: sorry...wrong thread...I was reading about increasing the compression by milling the heads down.

    Yes it can. You might need to mill .030 or more off intake side of head. And shorter or adjustable pushrods
