Unreal intake manifold cost

No I'm not building a race car. But I'm wanting to improve the performance some what, what I thought I'd do first is a carb swap, headers and maybe a mild cam something like a comp 268. If I go with different heads I'll probably get a set of speedmaster cylinder heads but that's later on. I think that I'd be money ahead by buying new heads rather than putting money into a cracked cylinder head
When you’re on a tight budget you have to be diligent about scouring your local resources, CL, OfferUp, etc. as well as hunting online. I like to build on a budget too, and lately I’ve been looking into 318 ‘torque builds’ that may net ‘only’ 300hp but 450+tq - by raising CR, good intake, carb and exhaust, mild porting and the right cam. That’s the goal anyway...
It may only be good for 5000–5500 RPM, but it’s plenty for a street car and won’t break the bank.
