Need my ls1 built or a new block
Newbie here! Please help! Alright guys my 99 ta needs a rebuild trying too decide what too do. Should i rebuild my engine or get a new block with the internals? Im looking too try too get close too 500-600 at the flywheel? What size should or need too go. Im sorta on a tight budget but i want stuff thats not going too break, prefer forged internals. What size do i have too go too get these numbers? I have heard iron block is the way too go but i have my ls1 motor so i dont know. Im going too put a fast intake-throttle body, msd coils-wires, headers on the motor so i know thats alittle horsepower. May put a super or procharger on the motor down the road. Where is the best place too get a motor and kit if needed and on the cheaper route but good. Please let me know what i need too do and what i should do. I live in Celina, Ohio 45822 if that helps at all. Thanks for helping, ramair1999@hotmail.com
Why do you need a rebuild? It you didnt trash your current block a 383 would be the cheapest way out for you. Have a local shop do the machine work and build it for you.
If you did something to the engine like spun a main bearing then its a different story.
I offer 408's with Callies crank and rods and Wiseco pistons, ARP, ACL race bearings for $4374 or for $250 less with a Scat crank and Eagle rods. It will accept your ls1 covers. If your looking at forced induction the iron block is more durable.

IN a radical setup Tony Mamo put down 543 or 548 with excellent tq numbers as well but that was an all out setup. Some guys put down 460hp with 450tq. SO the top end you put on it will make the difference. AFR's, TFS, ET, All Pro, Dart a decent cnc'ed LS6 head all if matched properly with a cam will produce some nice results.
You need to set a budget first and then look at things.
How much do you want to spend?

Ported heads and cam = 2000 dls + rings, bolts, bearings and 150 dls per hour from the engine building shop.
This would give you 370 ci and you could use the 900 you saved from forged crank and get nitrous, reuse everything else from your engine.
BUT after looking at the price from 99blancoSS, just get an engine from him. It would be cheaper than building one yourself, it will save you time and worries, all the parts which he offers look amazing besides he's got more engine building experience. I dont know but he even may be able to get the heads ported for a few more dollars prior to installation and save you some work.
Good luck anyways pal
