What to build?
What to build? Just looking for some opinions on my motor build.
I've got a set of stock ls7 heads with titanium valves and I'm trying to decide on what shortblock to build.
Car is a 99 z28 street car with 4500 stall weighs about 3250.
I'd like a low 10 sec car n/a.

With those heads I would build a big cubed motor, something 427ci or more. For $6000.00 you can get an LSX block and build a big bore 454ci or if you wana stay with the light weight alluminum blocks you can buy a LS7 block and build a 434ci or just buy a LS3 block and build a small bore 427ci. Anyone of these engines would make consideral h.p. and would be a beast in a car!
The cheapest route out of the bunch would be going with a New LS3 block and building a stroker 427ci motor. The problem is going to be that the LS7 heads are built for a 4.125 bore and I believe the biggest bore size you can get out of a LS3 is a 4.080 bore. I would say you would have to run a dome piston to bump the comression up.

Yeah thats really what I'm really trying to decide do I want a light weight ls7 block or do I want to go all out with the lsx block. I'd like to this car to stay n/a.

I'm thinking 415ci with an 6.0L iron block with a horsepower range of 550 to 600. With my new job, I don't have enough time to build a complete motor from scratch, perhaps I might just buy a short block.
I've been trying to get ahold of other sponsors on here and haven't gotten anywhere. I appreciate the info and I'll be giving yall a call sometime this week.
