any ideas what a stock gs 350 with 3:42 gears would run in the 1/4 mile? Oh yes it’s a hardtop. Thanks
google says 16.4. . https://www.automobile-catalog.com/car/1970/85055/buick_skylark_custom_4-door_hardtop_350_v-8.html
I’m sure someone who has run a stock small block will chime in. I’m going try the street legal sat Mission BC this summer. Plan is big block conversion in late 2020
We had a 65 slant 6 3 on the tree ran pretty good and I bet the gas mileage wasn't bad either. The GS I say 15.9 if it is a 70, 71 16.5
Take yours to the track if that's possible (close enough) and find out...…. WARNING YOU'LL GET HOOKED I did 15.1 first time out on street radials, 413 cam, 3.42 gears, spinning like crazy! Then with the help and guidance of the fine people on V8 Buick here, I widdled down to 13.65..... so far. I installed a roller cam, then spun #3 rod bearing, so out came the engine and upgrades began Hope to be back to the track SOOOOOON
If yours is stock,you are going to be disappointed when you are nowhere near 14.50's...I had a 70 4 speed 3.42 geared car with some added help and ran 14.55 in the 1/4 Aluminum intake,800 cfm carb,reworked ignition and 2 1/2 dual exhaust.Had a 202 cam or there abouts as well..Cr weighed 3800 plus change..But,it got better gas mileage than the GS 455 cars I was racing with..
If the motor is a 72 with all matching components and you have it initially timed at 4* BTDC, it will be an absolute slug and embarrassing. If you have it total timed to 32*, it wil probably run in the 15’s or 16’s. Take it to the track and see.
We forget how slow most of the old stock cars were. Most big blocks ran mid 14's. 350 4 speed Camaro's ran low 15's and they felt fast at the time. Getting into the 13's was a BIG deal.
Big difference between a 1970 GS350 and the 1971 & 72 GS350's. Somewhere in my vast achieves of old car magazines I have a comparison test of the 1970 GS350 and the 1971 GS350. The magazine wanted to see if there was any advantage to the new low-compression '71 engine. There wasn't...
Let me know when you plan to go to Mission Raceway. Might take my 1976 Regal Sport Coupe for a few runs. Nando.
I lucked out on my 72,by the time I got it my brother had blown the original motor and a 70 High Compression 350-315HP 440ft lb torque was in its place and later I souped it up good. I would slaughter the GS-455’s with it like the first 50 yards until they went by me like a freight train! I got my revenge when convoying GS’s to the beach & we’d be on our CB’s and they’d ask “What do you mean you don’t need any fuel?”
Larry, I will power tune it to 34 degrees by 3500-4000 rpm. I will go to the track just for the experience. It’s been on my bucket list for a long time. Will be interesting to see the time on a bone stock 350 versus the transplant to big block down the road. I’ve built the rear diff - Easton 30 spline, moser axles, solid control arms, polyurethane bushings, air bags, Johnny joints on the diff ears, 1 inch rear sway bar, 1350 pinion.......winter project - turbo 400, 9.5 inch stall......final part of build - big block transplant in late 2020.
