Default Help with my build-up.
I am new to the LS Engines, I want to build a mild to nice LS1 I have. 400-450HP without breaking the bank.

I have a 2000 SS long block (44k) complete. I want to go carbed with this motor. Heads, cam kit, oil pump, etc any help with making this motor last with some HP.

Thx

well. 400hp is as simple as bolting a set of headers on with the compleatly stock motor, TB to oil pan. if you're going carb'd, the edelbrock manifold is a great way to go, with the msd box. it makes wiring really simple. with just the victor jr and a pretty mild cam you'll EASILY make 475 - 500hp. stock heads.


if i were you i would do something like this...


http://texas-speed.com/shop/item.asp...d=174&catid=49

with a 228r on a 113 lsa. that'll give you a nice lope with pleanty of power, but retain pretty good manners. you'll love it. for an oil pump, i'd go with a texas speed ported or a melling ls6 pump. also you'll wanna get some kind of after market timing chain. and you'll need a gasket set.

have fun.

Thats a great start, but I think the cam might be a bit big for cruising. The car is not going to be a drag race car, but a cruiser and when I need to spank some ricer or 5.0 I will have the HP to do so.

I have 853's for heads, dont you thknk I need the 243" for 400-450 hp?

My list so far!!!!

LS6 "243" casting heads
Texas Speed high volume ported LS6 oil pump
LS2 timing chain
Thunder Racing 230/224 111LSA camshaft
LS7 lifters
Comp hardened push rods
Patriot Performance Dual Gold valve springs with titanium retainers
MSD plug wires
NGK TR55 spark plugs

Plugs are good, wires are good, lifters and pushrods and timing chain are good. Id get the stage 1 ls6 heads from TSP and a 228R. That way you arent buying heads just to switch the springs out.As for the oil pump just go with a melling 295. This with headers and a good flowing exhaust whould make well over 450hp at the flywheel easily.

no, i'd say the ls6's would be a waste of cah for your power goals. and if you're gonna do heads, might as well save and do it right with a good set of ported 5.3's or tfs's.


i dont think that cams too big at all. i think its perfect. the LSA is fairly wide for a nice idle & vaccume. that is a pretty damn mild cam, even with a carb.

my buddies car that i just finished tuning put down well past your goals with just a cam and unported ported fast 92/92 and a set of headers (853 heads, just like you.) the carb intakes make more power then the fasts, especially in the upper rpms. its a cam alot bigger than something you're looking for, and its still totally driveable with absolutly NO hassles, STALLING, no issues what so ever. we just took it to vegas and it ran absolutly perfect.

you dont need ls7 lifters or the double springs either. just stick with regular 918's and the stock lifters. if you really want the insurance the lifters could be swapped for new, but its not a huge concern. i'd also go with a 113 lsa. again, i think the 228r is perfect for you, but both those grinds sound good, unless you plan on spray. you'll want something like a torquer v2 or v3, and thats still a pretty tame street/driver cam, just a tad less mild then the others.


again, the stock heads are good to PROBABLY around 540hp in a MAX effort 346. 400hp is a totally stock motor with headers.

I just picked up a pair of 243's at a great price. Will these heads needs valve springs with the 228R cam or will the stock yellow springs work?

Thanks again for the help.

I would say pick up some springs, I don't know the exact specs on the 243 heads or the 228R but I think its max lift is somewhere near .600. If so you want better springs to be able to handle that kind fo lift, better safe than sorry and having to rebuild your heads again in the future. And I think the patriots would help with valve float too over the yellow springs, but there again I am still reading up on the info.

just get the comp bee hive's, the 918's. they're a great spring for this app. that that cam you'll defintly put out 500hp, unless you mean at the wheels. or another real nice street cam is the el torro. you can search it on here. that'd be another grind to consider.

Good luck man, I'm doing a 6.0 carb build and looking for 450hp and the wheels and a stock idle. For my 63' nova.

h8tulooze- Why you going with a reverse split cam? Are you leaving the heads unported? They are deigned for cars with little to no intake work and a GOOD flowing exhaust side.
