whatever you do to it can be transferred to a larger displacement sbc engine later on

other than boring it, etc

you could for now mill the heads or put on a dirt common set of the 80-86 years car and truck 4416 casting 305 heads,

port them yourself a bit,
polish the exhausts and smooth the runners to help it flow a little better, put 1.94 intake valves in it altohugh thats getting costly to have done these days, the valves are cheap though


but its really pointless for the most part with such a small bore engine as this

is it s truck hi-torque 307 or a turbo fire car one ?

theres a huge difference between the truck and car engines back thenthe truck ones were high torque output at a very low RPM whereas the car ones were more HP instead of torque

200 is higher than the truck ones

307 was from 68 to 73

327 and 307 are the same stroke crank yes
