    nascar block ? junior johnson built one and never made it out of testing ,

    hope the diesel block was stronger , 350 diesel has been gone for 26 years
    all of those cool winston cup 442 in 78-80 had chevrolet power
    Read thru this to find out a little more about the NASCAR block. I am not sure about the origins, just that these blocks were supposed to be for NASCAR use. If they actually made it to the track, I don't know. Plenty of the diesel blocks still around, even after 26 years.

    Twin turbo SBO's have been done for years.

    Adding twin turbos to a SBC- sure- see what happens!

    Yessir!...Daily Driver type stuff, good mpg and enough power to pull into the drag stip and not look like a chump.

    Interesting on the TBI stuff Randal. Does the MS stuff control the injectors on a TBI? Maybe I would be better off just using a carb....but then I think about the 2jet that's on the 307. Jet performance does some neat things and has them flowing over 500 cfm. I could make the motor look stock!

    I dug the cam I'll use out of the rafters .... 204/[email protected] 412/422 lift, should work nice in the smaller displacement.

    I say kill the bottom end so it hardly slips a tire on the launch and have it pull like a freight train after the 330' mark ... watcha think?



    that cam is perfect for a 307 it works good in 305 chevys too!

    If one more person mentions that CC mag before I get mine, I;m gonna'.......(lol )
    The thing about your small chevy heads is they will still out flow those 301 turbo ta heads (80-81)
    I think the reason for 2 smaller turbos instead of one bigger one is that they will spool up quicker.(build boost)
    Not going yo try to talk you out of it------- I'm an enabler

    Interesting that you say that- I am working toward a twin turbo Olds DX engine right now. I am currently just collecting parts- got pistons and the crank off ebay (some of the best aftermarket stuff dirt cheap!) Already have the block and all the external stuff, need the rods, turbos, etc. Planning on starting on it early next year. Won't be an inexpensive deal, though. I am shooting for 750 HP and making it live at that range.

    tbi runs at 9-13 psi

    Yeah the MS controls the TBI injectors. The injector issue is, I think the largest TBI injectors you can get for a standard GM TBI is 95lb/hrs, or 190lb/hrs worth of fueling, where as 24lb/hr injectors are probably as low as you'd want to go with a multiport system and that is 192lb/hrs worth of fuel. I run 32lb/hrs in the Skylark's MPI, and I currently have 85lb/hr injectors in the T-bird for 170lb/hrs of fuel. Now the trick is to see how many lb/hr's of fuel it'll take to support your HP target, then select your method of fueling accordingly. I don't know about the TBI, but on the MPI you can turn up the fuel pressure to artificially raise the lb/hrs of fuel delievered, because I think they are all rated at ~43psi of fuel pressure, so cranking the psi up to 60 get's you more fuel. Again I'm not sure about the TBI, though I know there is an adjustment screw on the fuel pressure regulator.

    At your elevation I'd have to go to EFI, simply because of the tune changes if you drive it off the hill you live on (like I do), or hell up that 11,200ft summit right next to where you live.

    I like the "because I have it" aspect of this.

    twin vs single I'm no help - I can imagine plumbing nightmares either way - it's all about taking time to think it out, mock it up and see what actually fits where, and keeping in mind the temperatures you're dealing with and the distance away from sensitive items that needs to be maintained.


    I would LOVE to see someone do a whacko junkyard turbo set up with an olds block - like one of the ones that was converted to diesel - E85, turbo - uber strong stock bottom end - and see how far it can be pushed before the block is ventilated....
