    Anyone have plans or parts to run the exaust side for a turocharged 350? Either a twin set-up or a single set-up.

    Thanks,

    Jim

    I would look at the GN exhaust system as guide. Full exhaust flow to a single location for the turbo. I'd like to see the 350 used in this manner, as it shares plenty with the 231 in design and construction. I think it would make a quite robust performer, and it does enjoy better block construction then the bbb. Good luck and keep us posted. Rudy E.

    Just finished the tear down on the motor. Still have a stuck balancer bolt, any ideas (TNT, Dynamite, C-4, nothing works!) I also need to locate the entire front end of an '86/87 Turbo motor. Brackets, mounts, & serpentine system. If anyone has this stuff let me know. I'll also be looking for '73-up cap screw rods.

    Any thoughts on pistons? I was thinking .030 over 231 turbo pistons (+2), along with my '69 heads (8.something to one) should allow for a modest boost level of about 6-8 PSI. This will allow the same performance as the NA455 Stage 1 I'm currently running.

    I'm also going to run the BRF TH200r4 (turbo t-type) and attempt to get into the 22 mpg range (3.31 rear gears, OR 2.25 after the OD kicks in!).

    I don't think this will get done before the power tour, so the BBB 4spd will just have to make do for now!
