Distributor Question

I think they called it turbo-fire...290hp for insurance reasons.

I think so. It was advertised at 290hp, but it was much more than that. GM was good a fudging hp #'s in the 60 and 70's. Due to Gubment regalashoons. Gubment had regulations on Weight to HP ratios to be street legal, so many times a car would be advertized at much less than it really was. Very common in Olds cars too, so I'm sure likewise in Buick and Pancho too.

Take the same tricks they used in that engine, and put them to use in the wee o five, and it wont be so weee no mo'.

NO doubt. It was the 30/30 Duntov cam, and high compression with big valve heads is what did the trick. That cam is actually quite radical for small specs. Not very good for mpg or emmisions either. You can damn near put a can on the tailpipes and catch raw gasoline at idle. I had a buddy that actually ran that cam and same motor specs with the same heads and all but ran the 327cu in. That bish flat got down with the program. With a Th350, he could be at a 40mph roll in 3rd coming up on an onramp, stab it, trans downshifted to 2nd and break the rear tires loose for a few revolutions and then when they grabbed, wheeeeeeeeeeeeeeeew !! GONE !!

ehhhhhhh, of course he was running 4.56 gear too, in a 12 bolt, lsd posi unit which helped alot. This was in a 65 Malibu. Running **** !!!

That cam and closed chamber heads....ooooof! Try to figure out a multiport system....would have to be MAF, not enough vacuum for a speed density setup. Get rid of the raw fuel, and zooooommm!

Pretty much was close chamber heads. You get down to 64 CC in Fulie 2.02 SBC old school head, that pretty tight. Also how you'd get to 10.5 and 11:1 compression and using a dome piston that had to be flycut so the domes didn't colide with the high lift valves.

Yes, for sure, today's technology is so much better than yesteryears. Sad part is, no need for bumpity bumpity bump bumpidity, or eyes burning exhaust to mean you're going fast. EVen when you do get a big cam today for an old school motor, the cam grinding specs have come so far with computer technology and more understanding of combustion and valve timing etc, even the new cam grinds for the old school motors are so much better. This is also how we get by with running pump gas. There's no need to be a cam techno guru and degreeing in cams anymore. The cam grinders and done all the work for you. Install the bitch, and line it straight up and run what you brung !!!

That's one of my all time favorite SBC engines is the Small Journal 327. 62-67 motors. In 68 the 327 went to large journal and cast crank. Actually the same EXACT block as the 350. The 327/350 even shared the same casting #'s for 68 and 69, then in 70, no more 327. Went to some ****** 307. JUNK IMO. Stepchild motor. But yes, ALL small journal motors, the 265, 283 and 327 were FORGED cranks. Those motors loved loved loved RPM. And they'd turn it quick too. And of course you know the story on the 302. YES, for you youngin's, Chevrolet made a 302. Not a quite a streetable motor though.

The 307 actually replaced the 283 in '68, I think it was basically a 283 block with a 327 crank if I'm not mistaken. It really isn't bad, it just never got any love because it was the base motor. I'd choose a 307 before a 305, it would probably wind out very nicely with a good cam and a good set of heads.

Yes, stroker 283 is 307, DEstroker 327 is a 302. I never liked the 307. Just another low performance cast crank large journal motor with junky ass heads.
I'd rock a 283 or SJ 327 any day over a 307 and even a 305. I'd almost even try a 267 over a 307 or 305. I mean if you're gonna have a sled, maybe get some mpg out of it.

Believe it or not, the 350 TBI heads are under 64cc

But the ports are jakced up with Nox bumps and so small they don't breathe.
