ok my stock lt1 just died, and i dont know what i want to do. i dont care about gas milage, emisions, but i do care about big HP, and reliability. i do want to be able to jump in it and go anywhere i want. it will b an occasional street car and a tough track car. i would like to get around 500 rwhp, and then put a 200-300 shot on it. i want to do this right, but money is a little bit of an issue, i would like to spend 5k or less, is it possible?

im open to any and all suggestions!

who do yall recomend? im in central tx.

 

500rwhp for 5k N/A = no sorry but you could build a decent shortblock make 430-450rwhp with a good set of heads even stock ported heads and a big cam and then spray a 200 shot on it and probably get close to your budget

 

You might be able to achieve the 500rwhp on a 5k budget, but I doubt it will be reliable enough to handle a 300 shot of N20. I would recommend that you go with a 383 block, all forged rotating assembly and sink the rest into a heads/cam setup comparable to an LE3. That would put you in the realm of 430hp, you could most likely work with Lloyd or another top end builder to design eactly what you need for your budget. I'd say the best thing to do would be sit down and draw up how much things are going to cost so you dont go over budget. I thought I could do my rotating assembly cheap, ended up well over 1k just for the pistons & rings, bearings, rods and crank.

 

I am going to assume that with your goal of 500RWHP for $5,000 dollars or less N/A on a LT engine that you are young and nieve. And why is it that you people want to add NOS ,even if you had 10,000 hp. Wake up son, and find another hobby.

 

sorry SON, a simple "prob not" would have been good! ive had nitrous for about a year now and i just like the feel. ive been into f-bodys for about 4 yr now, but i dont know much about internals, and bottom ends but im willing to learn! sorry my lack of knowledge bothers you, but you were here once too! im sorry guys but D**** like this really both me!

sorry i prob am a little nieve!

a major thanks to everyone else though!

 

Sorry you feel that way son. Yes, it is good you want to learn. That is the first step. We all have different levels of knowledge and experiance. If you use the search feature on this site, it is full of info. The LT engine seems to hit a wall at around 400-430 RWHP, with factory modified parts and moderate money spent. Any cubic in engine, the LT heads and intake hold back the short block from making any more hp and torque. From 430 RWHP to 500 RWHP , you may have to spend twice as much as you did to reach 400-430 RWHP and stay N/A with LT parts. Then throw in reliablity and up keep. It gets very expensive quickly. Is the rest of your car able to handle the extra power ? The fuel system, for one has to be upgraded for this. Many things have to be in order to be safe and have some life span.

 

Yeah the search feature would be a good source of info as this topic comes up alot...What are your goals? You want street, street/strip, or all track...Don't get too bogged down in hp #s as hp #s on dynos can vary significantly even though they are supposed to be repeatable.

Anyway, decide on what you want to accomplish and build from the rear of the car to the front first. All the power in the world doesn't mean anything if you can't put it to the ground reliably. I can't tell you how many supposed high hp cars have fallen victim to my little 400rwhp 383 in sleeper trim. Its all about the combination, period. I am partial to the 383 for great torque and hp without having to wind the thing passed 6300rpm. I also believe in forged internals and I have a Callies crank, Oliver 5.85" billet steel rods and JE pistons and they've been in the car for 11 years and 42000 miles most of which was 1/4 mile at a time...My rotating assembly is overkill and is a little pricey, but it doesn't owe me anything after 11 years...I also used Joe Overton/E.B. Porting at lethalefi.com but he's hard to get ahold of as he runs another type of business full time and does the head/cam stuff on the side as a hobby. This board also uses Lloyd Elliot and Bret (sstrokerace) for head/cam packages...Just keep searching and asking questions...That's what this board is for...Good luck...

....ps..sorry, just saw your sig and you appear to have the driveline/suspension covered...

 

what do yall think about this?

VRE 396LT1 Racer Shortblock-$3490.00 NO Core Charge
-Eagle 3.875” stroke 4340 Crankshaft, Eagle H-Beam Connecting Rods, SRP Pistons, Perfect Circle Rings, Clevite Main Bearings, Clevite Rod Bearings , Clevite Cam Bearings, ARP Main Studs

93SS, yes i already have a 12 bolt 33 spline, spool, i also have the 255 in tank walbro, and a custom built cluch supposed to handle 500 rwhp! i have used the search feature some but i was wanting to be more specific in what i was wanting to do, thanks for replying back with use full info... i was just wanting around 500, 460 ish would be fine. also nitrous will be in the future cause im having to sell my kit that i have now to build my motor, plus it a nos kit !

 

It gets expensive quick.

I am doing a 355 and reusing my valvetrain. Still spending Everybit of $5k on it.

 

Here is a spreadsheet that I put together while I was building my motor. So this will give you a rough estimate of what you can put yours together for.

Big power is in the heads and intake with matching valvetrain. Reliability is in the total package, getting everything to work great together,not just throwing parts and money at it. Sorry ,I missed your heavy duty driveline parts. I cannot stress enough about planning what you want. How much money you have to spend, and how driveable you want it to be. It is all in the combo of parts working together. But, as you already know by now, 500 RWHP n/a in LT type engine for $5,000.00, is not going to happen. Good luck with your project. Talk to someone like Bret Bauer about your combo and money to be spent. Take care.

 

i'd say for 5k all you will get is a good 355 short block and a nice heads and cam setup. Unless you up your budget you aren't going to be able to have a stroker.

 

I agree, chances are you will go over that 5K with the basic 355 setup with a good heads/cam swap and supporting mods. Mines a budget build and I went over.
