big hair dryer is barely spinning and it isnt heating anything just cruising.
what is the expected weight of the car? a 370 should be fine with the 88. If it were my money, i would do a ls2 block with doweled mains......save a good bit of weight that way and still meet the hp goal you will need.
Heads are gonna be costly but you can find some good deals used to save some cash. You will need the thicker decked aftermarket castings like ETP..AFR...etc

Of course, front-mount w/ the charge pipes not being near the exhaust could be a very different story.
Anyhow, just my $0.02

I will politely disagree w/ that statment concerning heat....as 5K miles worth of data logs showed it didn't hold true for my rear-mount setup. I had to run a FMIC + an electric fan on the intercooler to keep things in check during stop/go traffic. (Keep in mind I'm talking IAT's here and heat soaking from traffic and low speed driving, NOT engine coolant temp.) Guess it also depends what you're comfy with. I didn't like IAT's to exceed 15 over ambient at any time (pulls timing) and didn't feel good about resetting the IAT spark retard threshold above 110.

i had my sts at 5psi and it was super DD.
i as well am lookin at the s88-s91 for a 370. in my head either will work and im leaning to the S91 same reasons less boost same power, and room to grow.
go 91 and never look back

when I say street driven....its not a primary vehicle honestly, it'll be brought out for meets, cruises, etc. for fun. Don't see a problem with that at all.
I may juts run the truck head setup with an 88.
weight? as low as I can get it with the Iron block....still thinking about ls2 though.
to many different ways to go.

What kind of rpms are you going to try to spin? If you're looking for something lower that low to mid 9s in the future I would look really hard at investing the extra money required into a, lets say, 8000 rpm valvetrain top end. Whenever I change anything up on my car, I try to go a little bit overboard, because I know I'll always be looking for some more power here or there on down the road.

if you plan on keeping the car and are the kind of person who can't leave good enough alone, what may seem overboard for what you want now will not be overboard for where you want to be 1-2- or 3 years down the road. less money in the long run too.

Well your BIG thinking is another $8-10 K. Thats 1/2 of his whole budget.
I know I have a solid roller going togeather right now.
Have you priced Jessel rockers latley??? $2k for just them.
Dry Sump.... Price that out.... $4k......
Im like Hunter. Did Bottom 9's on stock rockers....

I see where you guys are coming from and forgot about his budget and yea I understand the cost of it all. When I look at my project, I don't see it getting done until the year 2093 with my broke *** but I have my goals.
I think he's definitely on the right track for a killer setup though.

I would go S91......BIG power, quicker spool then any other turbo that size, and will make 800-900rwhp on pump gas with the right combo. If you want just a little less the S88 is no slouch either...Na$tyTA above made over 1100rwhp with his S88 on a PG tranny.
