High MPG SBC Build

[thirdstreettito]

Well, my 88 TBI 350 with 146K miles gets 12mpg city. Pretty sucky eh? It needs at least one head gasket. I was planning on swapping the heads/intake over to Vortec stuff when I do the head gaskets. But I think I may just rebuild the engine. I want MPG's. When I do the engine I plan on installing my TB spacer, injector spacer, adj fuel reg, and a TBI rebuild kit.

From what I've read so far, high torque engines get better MPG's than high hp engines. I hope to achieve 15mpg city at least. I'm planning on doing .010 over, but I'll find out when I get the engine out if that's enough, as I cant see cylinder wall damage/wear until the I get the engine apart.

So my question is, how would you build this engine? It MUST be in total under $1000.

I was thinking, Sealed Power .020 over engine kit with hypereutectic pistons and an ISKY 262 supercam. I dont know about pistons tops though, dome? flat top?

I also dont know about rod bear undersize, I am new at the specifics.

I was thinking one of these kits - http://www.summitracing.com/search/b...Asc&rsview=SKU
