1973 360 upgrades

Search engine builds on here by member @IQ52. He shows first hand that you do not need high compression to make power. His builds usually include very professionally ported heads, but with good parts choices, you can make very respectable power with stock ports. I would do the mods you've said and see what happens. With one caveat. Use headers and the 750 Street Demon instead. A 360 will suck that carburetor down like a Hollywood hooker.
