Since I for the life of me cannot get a big block build going due to the fact that I cannot find one locally and no builders around here can I'm going to go with a small block build. This is what I've come up with and I'm looking for any opinions on the setup I'm thinking. I'm hoping for around 425hp or so.

-GM Performance 4 bolt main, 1 piece rear main (NAL-10105123)

-Eagle Specialties rotating assembly, cast steel crank, forged I-beam rods, hypereutectic flat top pistons (ESP-B13402L00053)

-GM Performance LT-4 "Hot Cam" 218/228 duration @ .50 inch lift, 0.492 int./0.492 exh. lift (with factory rocker arms), 112 degree lobe seperation (24502586)

-GM Performance Hydraulic roller lifters, with spider retainer, and lifter link bars (NAL-12371042)

-GM Performance 1.6 ratio self aligning roller rocker arms with polylocks (NAL-12370839)

-GM Performance 7.122 length pushrods (NAL-12371041)

-GM Performance Fastburn cylinder heads, 62cc combustion chamber, 210cc intake runner, 2.000 intake valve, 1.550 exhaust valve (NAL-12464298)

-Edelbrock Performer RPM Air Gap intake manifold (EDL-75014)

-Cloyes double roller timing chain/gear

-Moroso 7 qt oil pan (20205)

-Milodon standard volume oil pump (MIL-18755)

-Milodon Oil Pump Stud Kit (FREE WITH OIL PUMP)

-Quickfuel 750CFM carburetor (QFT-Q-750-PV)

It's pretty much a Fastburn with the LT-4 hot cam. Total cost would be right around $4,250.00. What do you guys think?

i think

that cam might leave some HP on the table ,,, call around ,,, i've read about some 383's making 500 hp and over 500 ft blbs of torque with a hyd roller that isn't that much bigger than that cam. Unless you really like something that idles smooth ,,, i'd get a hyd roller on a 108 LSA with around 235 @..050

here is some interesting dyno combos you might want to look through

Definitely shop around more before you start buying parts!! The part # you have listed on Summit's web sight is a 355 balanced rotating assembly. If you look at CNC Motorsports and AD Performance you can get the balanced 383 rotating assembly for about $30-$50 more and they come WITH a new balancer and flexplate which MORE than offsets the extra cost.:yes:

The old "Hot Cam" is antiquated at best. Give Lunati (or better yet Harold Brookshire directly) and get a better cam.....Probably cheaper as well!!

For the dollar spent, There's a LOT better cylinder head options out there. A set of AFR 210 Eliminators are in that same price range and will run circles around the old "Fast Burn's"!!:yes:

Same goes for the pushrods (call Smith Brothers or Trend Performance) and Lifters... Competition Products has their Howards branded Vertical link bar hydraulic rollers priced in that range and are a LOT better lifter for high reving applications.

Rockers can be found cheaper as well.. Scorpion or Harland Sharp rockers will cost about $100 less than the GM rockers!! Especially since the aftermarket heads won't require self-aligning rockers.:yes:

Just a few ideas... Yes, 500-550 HP and over 500 lb/ft of torque is easy to get with the right parts and doesn't necessarily have to cost any more than a comparable engine built up to 450 with the parts you have listed.:rolleyes:

You're looking at about $5000 by the time you gather up all the pieces---you can almost buy a 383/425 h.p. crate motor with a warranty from Chevy for that much--or a crate from several others for less.

Yeah, there's no way piecing it together from parts, especially if you buy retail from Summit or Jegs, is going to be cheaper or better than just buying a crate engine. You'll get a well developed engine package with a warranty.
