The 302 can be built with a crank from a 283 with a 350 block destroking
the 350 to 302 cubes. If you are after power with this combo you will need
the right heads and cam setup. Also they ran high compression (11:1, also
solid lifters for the cam and maintance for you)
With that said they make tons of HP. but are a little low on bottom end TQ.
But will that thing scream when you get it wound up.!!
I rember them well from the 60`s. They were as bad as you could get in a
small block but are prone to blowing up if you push them. ( you can build
you a 327 by using the 307 crank in the 350 block)
As for the 307,I had a New one in a 69 camaro, was the biggest pece of Shit
I ever owned Gm should have to still buy them things back!! My 2 cents on
that!
If you want driveabilty and good miliage try a new gen. 350 with FI the
roller motors of today are much better in performance and durabilty for
every day use.(hope I don`t start a flame war here)
