    I really appreciate that!

    I'm sorry I don't have a real update.. just relocating the battery to the spare tyre well, nothing fancy.

    Waiting on the tranny for my Cummins powered Ramcharger

    Been a while gents... Finally a little progress, albeit nothing fancy:

    Sanderson 300 headers modified for the single turbo setup. Turbo will be where the battery was (pass side on non-nailhead '65's). Using a Land Rover Discovery front cover for the better oil pump and more compactness of filter location for crossover clearance. V-band connections for crossover with flex joint built-in as well as flex joint from 2-1 collector into turbo.

    wish they were larger.. Sanderson only makes 1.5" primaries and 2.5" collectors for the 215/300/340.. If I wasn't so cheap and lazy we'd make a full new set with 1.75 primaries, out of some $$$ stainless or inconel.. someday with my street race winnings:Dou:

    As you can kinda see, the passenger (formerly driver's) header didn't need any modification other than a v-band. The driver's (formerly passenger's) needed extensive modifications to fit, even around a manual steering box.

    Thanks for the update, good to see you back on v8! I was getting a little worried something might of happened to you.:Do No:

    See Andy, the turbo route doesn't look that bad even easier with a treefitty because a set of sbc turbo headers can have the sbb 350 flange welded on them and down the road!:Brow: And maybe a set of altered sbf turbo headers for a 215/300/340 might be easier for anyone thinking about turboing their car with one of those engines.(not sure haven't really looked into it but for me making a flange would be easier than the tube work but that's just me)


    Looking good Wes, is there any plans of rebuilding the engine before the boost or are you going to boost as is? And how is Ansel doing, 100% now I hope?

    Already tryed the sbc headers . Buick exhaust ports are way to close to frame and upper control arm . first 2 pipes need to have really tight bends off flange on both banks. It can be done just not as straight forward as I thought.

    I'm talking the sbc turbo headers that go forward. Something like these;

    Derek,

    I am okay, I appreciate the concern. I was/am just REALLY busy with my REAL passion, steamboats and steam machinery, as well as schooling for the fire department. Our fire season was quite active! 2 weeks on the King Fire was a icing on the cake!

    Ansel is 100%, though he shut down his shop up here and is partners with a friend down in Carson City now. That was another one of the holdups with the project... Money is always an issue too

    I will have to at very least rebuild this engine, as when I removed the stock intake to install the sheetmetal one I discovered why I was always chasing my tail with timing and carb tuning; flat lobes on the cam:( I have a set of 8 forged 3.8 BV6 pistons on the shelf waiting to be flopped into the engine, until I aquire the $$$ for the billet and forged stroker that is...

    As far as what he's saying about the sbc headers, I think there may be a issue with the orientation of the exhaust ports on sbc vs sbb due to their orientation in relation to the deck (45* vs 90*) EDIT: ah i see the up-n-over... still pretty tight turn for a sbb...

    I looked into sbf headers and even bought a cheap summit set. They still needed modification for the driver's side and also lengthening due to different port placement, so BOTH would have to be extensively modified, as opposed to just one...

    Good to hear your friend is doing good, sorry to hear he moved away. I'm glad to hear all is well with you and my holiday wishes go out to you and everyone on bv8!

    That angle difference can be made up when the new mounting flange gets welded on with the sbb 350 to sbc headers not a big deal they just need to be fitted in the car before final welding. And how about a set of LS turbo headers for your 300? I will do a search and see what they look like and maybe post them here in a bit.

    How about these;

    These are up and forward like the sbc ones are that I posted and look easily modified from someone with your skills. If you can't buy it make it or alter something to work = Hot Rodding.:TU: The tubes on these look better and they don't really cost that much.:Brow:

    And if the lobes on the cam are wiped out just swap the cam for now and just keep the boost low until you can get to engine?

    Those are nice looking pieces for a nice price... i suppose it wouldn't be too difficult to modify those.

    I left the intake and front cover off since I found the issue.. a bit of unwanted moisture and dirt in there now (1+ year later:Dou: so no chance in that...

    Closer...

    AND YES, when this is up and running, it will be going straight to the track (after tuning of course) with the STOCK transmission and STOCK rearend ( STOCK axles with welded carrier aka "Lincoln locker").

    The engine, which is at the machine shop, will have SCAT I-beam capscrew rods (thanks for making me see how foolish I would have been Derek), stock crank, cheap speed pro turbo 3.8 forged pistons, and stock-ish heads... This block might have one of Gary's girdles, or I may save that for the later build.... Either way, I'm going to run the piss out of it, see which happens first.. I break it or the "super engine" is completed!

    I tried the break it or super engine is complete move on my Skylark, and the super engine (my case a 455 to replace the 231 V6) finished first. I tried blowing up that 231 too. You'd think ten minutes of WOT, at ~4,200rpm with 240+F temps and sub-5psi oil pressure would have done it (climbing a 6% grade in 110F outside temps), but after doing that three times it was still purring like a kitten.

    What a great thread!

    Its been a while since you started this thread I'm glad your so close to get that wagon to the track. What rods did you end up buying? The 6.00" sbc small journal rods? Don't forget that they need to be narrowed on the big end before they're weighed for balancing. Can't wait to here how it does on the track! GL

    Derek,

    Thanks for the kind words! It may still be a bit before I burn rubber in anger! I am going to be working for two fire departments this summer.. Fallen Leaf, and I just got picked up by Cal Fire... Cal Fire will have the priority though! So, finding time will be a trial for sure! It's definitely closer than a couple years ago!

    I got the 6" small journal rods, little ends have been narrowed already, and the machinist found that SBC bearings will work with no further mods!
