Anyone got the engine spec's on a 80 350x??? HP & TQ Also does anyone know the gear ratio's in the 80s turbo 350 Matt uzzled:
The NHRA site says the 4bbl 350 rated at 165hp with a 9.06 CR, no mention of the torque. The fuel-injected 350 only rated 105hp.
David where did you find that?? Do you have a link. I search all over the web for Buick engine info but Didn't find anything past the 70's. Matt uzzled:
Here's the NHRA link. Go down about halfways on this page, and there's a box labeled "Racing Information". Click on the link that says "engine blueprint specs". Then scroll down to the Buick section, and select the model year. Lots of good details in there! http://www.nhra.com/index.html
After looking once past 1972 the 350 never had more than 150-195hp and 1980 was a good year when you look at the rest. The best year were, 68 230hp / 280hp 69 230hp / 280hp 70 260hp / 285hp/ 315hp 71 230hp / 260hp 70 would be the best year as you know your getting atleast 260hp with out much trouble. ----- 1980 H.P. Disp. C.R. Head cc 165 350 9.06 66.35 Deck Piston Type H.P. Disp. Cl Dish/Dome Ht/Vol Cam Lift 165 350 .002 Dished .131" 11.86cc 474/474
I really Don't know much about engines but once I start to compare the head cc and the cams, I could have as much or more hp than any year 350 or close to a 403-455 if I just raised my compression. http://ViragoTech.com/BUI-68-82.rtf Matt uzzled: chop .010 off the deck or use a .020 instead of a .030 gasket???
That NHRA site is crap for info, it has cause a big ruckus from its bad info. "David Butts Senior Member Registered: Mar 2002 Location: orange park fl. Posts: 132 NHRA specs are for what you are allowed to do to a given engine combination under their rules to ensure that their factoring equations keep different engines from different manufacturers competitive in a given class. In no way can those numbers be misconstrued as the stock specifications from the factory. Thats how Joe Blow from nowhere minnesota can run his 72 skylark 4 door in the stock class at a 12.50 with stock parts . The word "stock" in nhra terms really means nothing when comparing real world engines. How many "stock" parts do you suppose there are in a pro stock car?"
