Buick Grander National?

- The Boat Anchor Buick 350 has been completed, efi is installed and we get things ready to hang a cheap GT45 Turbski right off the front of this bone stocker just to see what the 80's Grand National 3.8 Liter recipe does to it's Bigger and Bolder Brother!

These videos are awesome. Informative and captivating. Thank you so much.
Glad you like them!
I'm Blue Oval for over 40 years, but the GN was the most successful execution of a factory hot rod. Like a USA version of a WRX.👍
I guess a 300 would be closest to a 3.8 with two extra cylinders. I can't wait to hear that thing scream!
Yeah, they have the same style of exhaust port. I put a hot air turbo regal header on a 300, and it just needs some length in the middle of the log and a 4th primary added. A turbo 300 would be cool too...
@@HSTvids357 Probably be easier to actually build one from tubing stock and some flat pieces, like you would a set of headers. Just build it in the log manifold format instead, and it will be way easier than headers with their long primaries which need to be carefully routed.
If you run the oil drain back to the timing cover you can send extra oil to the distributor gear and timing chain. Probably would be a good idea to run the oil through an oil cooler first so it's not super heated turbo oil draining on the distributor and cam gears and chain.
This would make it super simple for the guy doing this that has the engine installed in the car already.
And the number 1 performance upgrade for a sbb 350 is good pistons that aren't .080" in the hole with a head gasket installed. The pistons that AutoTec makes for the sbb 350 work great.😎👍
I have a bone stock 63 skylark and even with a 2 speed auto it isn't slow. That thing is going to haul ass.
👍👍👍
I firmly believe that with a girdle, forged bottom end and rotating assembly, with a haltech computer and coil on valve covers like the LS along with some hellaciously worked aluminum heads and intake, you can make a 1,000 plus hp with a turbo OR an F1X pro charger and of course intercooler.
I understand that you are doing it on a budget with parts you already have mostly.
I’ve been wanting to do this for years but money tied up in business and not expendable has kept me from it. I’ve got 2 GNs sitting here a hour away from u on the TN/KY border. Sold all my V8 Buicks years ago. Inherited a GN last year.
The GNs would start detonating over 14 lbs boost even though the stock waste gate was actually set at 16 lbs of boost so we had to back them down back in the day to get more efficient performance. I’d start at 14 with good octane. Only downside is you don’t have the forged internals.
Look forward to seeing your progress.
i have the 350 i had in my skylark before i swapped in the 430 and i was thinking about going turbo and popping it into a skyhawk so watching allong with great interest
I've completed that swap of 350 SBB into 1976 Skyhawk. I put it together in the late 1990s and still have the car. I take it for a spin a couple times a week. Try ks_skyhawk
If you get the v6 HEI for computer control and swap the ring, pickup from like a chevy v8 and the 350 ti.ming gear you have an easy efi distributor. I sis this for a 455.
You're getting gooder. Run ls coils so you can vary timing cylinder to cylinder.
This is gonna be really cool! Can you say Torque
My estimates based on stock 1973 Buick 350 factory ratings and 15psi of boost. It should be close to 520hp and 740 ft/lbs.
Interesting video. I’d be curious as to how that engine would run in your Suburban. Especially with the twin pitch. Fuel mileage and torque?? Maybe.
I was gonna dyno the engine once completed. That all depends on money.
Any plans on what sort of vehicle top put this in?
I had an s10, but it went away at the beginning of the year.
@@mr.roddersneighborhood2740 I can't wait to see what you come up with!
Been laid up with bad hip and back pain. Operation for hip replace feb 13. Hope to then get back to the opel 69, and bored stroked 215. Will send pic of parts if interrested. 78yr young. If your interested. With plan of attack. Have questions for direction and/or what would i need to start a build channel.
OldeBuick in rensselaer, Indiana.
I wish you the best of luck with your operation. A 215 stroker is very cool but have you considered using a Rover block? You can get one of those with a 3.700" bore. If you didn't already know about D&D in Michigan, they have lots of info and products to help with your build.😎👍
Just remembered, they are in either Almont or Imlay City, Michigan.👍
Worked allied auto supply 60-70 restored Olds blocks for scca classes but used buick heads.
Before I went to usmc got 215 buick bored sleeves ou and proved head to hold top left for boot. Got back forgot about it. Went into banking. Couple years ago shop was closing and the contacted me. Gave me block new custom manufactured sleeves for 305 pistos 60 over. 5.7 chevy custom rods, custom castv305 Pistons, 300 crank ground to fit. Crank wiper with builtin parameter to tie main bolts and sides of block togetter.
Have work on oil galleys converting to do oil through push rods. TA heads, rockers, oil pump and front cover, ami custom damper, gnx hall effect for coil on plug, crossram intake with 8 throttle bodies and injectors. Hall sensor for crank, 2 knock sensors (1 each bank). And a British fast80 control box. TAPerformance electric water pump. And 1.6 (true) roller rockers.

That's an awesome list of parts!😯
D&D does sell the rear main conversion gizmo when installing a sbb 300 crank in a 215 or Rover block.😎👍
So is a giant turbo on a 455 the grandest national?
By the math I used, apparently yes!
