probably not vorte heads. gonna pull the top off and try and figure it out. it has at least 300 hp. I know that one for a fact, i have a 72 chevelle as well and with its modifications comes out to about the same amount of power. I have to get it dyno'd. the chevelle is 320 right now

Not to be argumentitive, well...maybe a little, but isn't yours a 3rd Gen camaro? Back seat? Carpets? Headliner? Pw windows? PS, pb, ....unless its a Max effort gutting, its 3000# plus.....f-bird....correct me if I'm wrong here.....that being said, still could be a rocket ship....especially compared to a d15 civic or the like.....
haha funny enough you nailed the civic engine. and hm maybe your right. the scale we have around here i can't say is the most accurate.old junkyard one.

Ah they wernt all bad, I had a d16z6 in a coupe and it was a blast to drive, 7000rpm everywhere and your foot on the floor always.....can't do that in a "real"car without getting arrested or dead lol......see if you can track down a parts list on yours, and pull a valve cover, grab the head casting number if you get a chance.....be kinda fun to see what you actually have there. It def looks pretty tho.

I know how that is.....I have a terrible habit of forgetting I'm actually almost 40. A fact my wife feels the need to remind me of every time I do something foolish. "You know your almost 40 right" said with a bemused expression on her face is like the mantra around my house....or the garage, or on a snowmobile, or in anything with some semblance of horsepower.....she keeps me from getting dead or arrested regularly....

Hahahahahah......that's fantastic....
I had a 4eyed GT about 8yrs ago, normal bolt on's, ten minute tune up mostly but with 373's...anyways, me and my boy, he was maybe 7-8 years old, we would just tour around my little village on a Dplate, couldn't afford to plate the stupid thing....so we would just go on small tours....small burnouts, nothing to bad....and he knew not to tell mom if dad was being "silly".....outside our town arena, showing off for a buddy, giant humungous 2nd gear burnout, t-top open, the damn wind caught us and absoluly sent all the smoke back into the car....it was sooo bad. Got home, he went inside, 2 seconds later she comes screaming out the Backdoor bellowing about how my kid reeks like burning rubber and there is black "dust" in his hair........I nearly fell over laughing......ahhhhh.....I miss that car....

.. I agree, about 250 - 290grossHP... nominal 8.5:1 but prolly actually 7.6:1 compression ratio... hence the poor MPG... domed pistons would pump HP up into 300's and 17-20 MPG... GM sells a Mexican SBC 350" crate engine built to mid 1970's spec's rated 290grossHP wimpy 330 lb.-ft. torque using 224/224 duration cam from 1960's L46 350HP 11:1 350" 'Vette engine.

.. Nova police cars were popular around here for a while... prolly had LM1 4bbl. 350" engines of 155-170netHP depending on exhaust setup... 225grossHP at 4200 RPMs with open headers... SBC 400's in those days rated 175netHP at 3600 RPMs... in '76 - '79, Nova 4-door bodies were stretched 4" between the doors to make midsized Cadillac Sevilles with EFI port fuel injected single plane aluminum intake Olds 350" engines, 2-bbl. throttle body, low compression, prolly about 155netHP...

.. After GM dropped the Caprice in 1996, they tried to put cops into Suburbans... some places out west and south used Camaro/Firebird and Mustang police cars... Big Buicks were made in Flint. Michigan and Flint used Buick police cars... Jeeps are made here and police/fire/city use some Jeeps...
