Re: sbc 307?

Do you really wanna go hy po? It starts to get into that grey area where you might as well go with the 350. But then is that enough. After that you start blowin the drivetrain and when does it all end? If you have a 307 and it runs good I would invest in mods that guarentee long term viability Not peak HP.

Timing chain set, oil pump, damper , HEI and a MSD 6AL. and she's good for 100,000 more miles. If I was going to rebuild one for the sake of origionality Then i would still stay close to the stock theme and maybe...again focus on quality, blueprintingand long term reliability. Anything more and you might as well go...again with a 350, and will that be enough or should you go with a 383 , aluminum heads, headers ect,

Deside what you want to do with the truck at the beginning and stay away from those speed parts catologs or it will never end!

Re: sbc 307?

if my truck had a good ol' 292, i wouldn't replace it with a 307. i like the 305 better because it has the same crank as the 350. the 307 has a 3-1/4 stroke and is basically a 327 with a smaller bore.....not much fun in a truck. my 72 burb 3/4 ton 2wd has a 307 with saginaw (column shifted) with 4.57 gear in the back. i will be putting a q-jet on it for the short term but i have a bad boy 406sbc to go in eventually. i will say that 4.57 gears are a little too steep around town, even with the that little engine. my dad pulled our 6,000 pound '71 holiday around with his 72 burb with 3.73 gears (automatic) for years so i know that the q-jet and 4.10 gear swap will be enough for the short term. right now my best gas mileage is 10-11mpg due to no overdrive but i have plans for adding the factory od to the saginaw in the future and that should get me up to 15-16 atleast and quieter highway cruising.
