The engine is a slightly warmed 454 with 71 open chamber heads, and approximately between 9 1/2 -10 to 1 compression. It is basically a LS-5 motor with one of the "Old school" Edelbrock C-396 Aluminum Intakes, so it will look like an LS-6 motor but it's not. That intake will fit perfect under the cowl induction hood by just leaving out the spacer. The trans is a TH400 and it has a 3.23 or3.31 (I never remember which) 12 bolt chevy posi. The car is being built to be a nice driver, not a race car. Hopefully it will be done some time early next year. Duane
I bought the GN roughly 3 weeks ago. I feel bad putting my 70 GS on hold but I have fallen in love with the turbo car. Someday the 70 will get done, I'm in no rush. Anyway, keep the updates coming, I'm signed on to this thread!
A couple quick notes. This car has actually been off the road since 1993, so 21 years as opposed to 5-10 like I thought. The guy I bought it from said he started having the interior redone shortly after he bought the car and I found a receipt from Year One from 93 so that's interesting. And also I found a set of Keystone wheels near me for a good price like the one's below. I like them but would they look good on a Buick? If anyone has any pics of a 70-72 GS with these wheels, I'd love to see them. Thanks.
Wow. I can't believe it's been a year since I updated this. I'm sorry to all who were following. Sadly my plans have not come to fruition even close with this car. Around the last time I had updated I had just gotten front floor pans and a cowl patch panel for it and now I also have a core support replacement panel, but something else came up. The 1970 Olds Cutlass we'd been working on since 2008 was just about wrapped up. Then we tried to drive it down the road after the car was assembled aside from the new Ram Air Hood that had yet to be painted. When we got back the new paint on the intake had bubbled off due to heat as both upper and lower radiator hoses were collapsing on throttle. Ugh. Then we did a compression test and the number 7 cylinder had ZERO compression. And thus started the viciously expensive cycle of rebuilding a motor. We took the top end of the motor apart and found the valves had seated way up in the heads from running Unleaded gas without hardend valve seats by the previous owner. Double UGH! So we had the heads redone and decided to put the bigger valves in them. Then we made the decision that if we're doing the top end of the motor, we need to do the bottom. So we pulled the block. When we got it on the engine stand and turned it over, we heard a clanking noise. As it turns out, the oil pickup was just sitting in the bottom of the oil pan. Fun stuff. Moving along we decided to go with a new Edelbrock Performer Intake, Hedman Hedders, Holley 670 Carb, and a Mondello W-31 Cam. Originally it was going to be a stock rebuild but you know how that goes. So to tie this together, the Cutlass is kind of my car, kind of my dad's car, so both our funds and time have gone to finishing this Olds. On top of being busy with school and having a two month long bout with Pneumonia that got me way behind on everything, I haven't gotten much done with the Buick. It's disappointing but it is what it is. And with the Olds not being operable for a year has also tied up the garage bay I can work out of and I can't exactly cut the old roof panel off with it outside. The Olds is now up and running and sounds great. It should be road ready in about 3 weeks so after that I'll be able to finally get back to the GS. P.S. -- I'll put some pictures of the Olds up once it's done if you guys are interested. It's a pretty car.
