396lt1 need to beat bolt ons ls1
Ok all so i've been on here for a few months now and basically just overview everything for research reasons but i'm in need of some expert advise......so my woman just went out and bought a 99 ws6 auto with a minimum of headers and good flowing exhaust. Supposedly has a tune as well and is said to put down 375 rwhp. I too have a ta but is only a 96 lt1 which is knocking right now anyway. So my question is as follows.....(please spare the ls1dominates for this I know it's an awesome engine BUT I DON'T HAVE ONE LOL) so what I wanna do is a 396 stroker build ( i've done a 383 before non lt1) with port work on stock heads, port work on stock intake with bigger throttle body, long tubes and a full exhaust. OR just freshin up the block and run 3psi ish from a remote mount turbo.....I plan on using the ebay kit for this project since money is a factor hence i'm doing as much port work as possible to save on heads. I have a second set to work with so if I screw those up I have back ups. I also have a set of 410s for it as well. I would think a 396 with decent porting and bolt ons would walk a bolt on ls1??????....right? C'mon guys don't let me get shown up by my woman lol!

I haven't seen to many bolt on ls1's put down much over 340-350ish on the high end...Most that are over 370 usually have a small cam or ls6 heads..
I know you don't want to hear this but the money you spend on the stroker LT why not find a LS2 block and go that route?
If money is a factory and your looking at a power adder nitrous is a good route as well for the LT.
FWIW My bolt-on stalled auto LS1 car (at the time) went 11.89 @ 114..

If you run hand ported LT heads on that cu.in that will be your restriction....Her car with even stock lS1 heads will most likely RPM better then the stroker LT and she may get you on the big end...
Another thing to think about is traction...If she is on street tires and your on a decent drag radial you may get the hole shot and hold her off....for a while

I would love to do an ls swap but I figure for the amount it would cost for the base power plant I could add a lot of ponies for 3k.. and nitrous was another option I was thinking. Just building a strong stock bottom end and spraying or doind a remote turbo setup. Either way I'm rebuilding the bottom end and I think next winter id splurge for ai heads because I've seen nothing but good results from their work...I think the ls swap would nickle and dime me to death

Youre over-thinking this. If your wife is going to stay bolt ons only, you only need heads and cam to walk her. Check out lloyd elliot's website and he can set you up with a good setup.
A stroker and turbo is overkill and if done right, it will be very expensive.
BTW, i really doubt a full exhaust and tuned ls1 is pushing over 370rwhp.

Yeah I thought that 375 was a stretch and didn't really believe it too well but I do know the ls motors put out well with just bolt ons. But I would love to do just heads and cam set up....between long tubes and the exhaust I already have with the 410s and a few other small mods I just wasn't sure iftthat would do the trick.....I figure I have around 3 grand I can put to this challenge.....so if I did just heads cam I think i'd probably throw a small amount of spray too the question is do I lower compression a bit to allow for future bigger shot or keep the stock cr? ......I know there's a million different combinations to do this I just want my biggest consistent bang for buck and all the labor is free minus any needed machine work.....so any and all advise is much appreciated.

Well I have an amazing machinist that's super cheap so i'll get by the bottom end easily but I did just look at the lloyd heads and cam package and stumbled on a vette forum where a guy dynod 364 rwhp off that set up and for the price that's probably the way i'm gonna go. Thanks for that info i've been reading that he puts out just as much as ai but a much more reasonable price. I'm just wondering if I should gotthe bigger injector and walbro or if stock will do it......either way getting it tuned is gonna be the biggest chore i'm in podunk iowa lol

Start with the basics, bolt-ons and supporting mods, have your heads ported(I don't recommend doing it yourself), and then get a custom cam from a reputable vendor.
If you need a big stroker to beat a bolt-on LS1 your car needs to be burned!

well i should mention that my beating her is all in good fun, as when we get married we drive off in the winners car lol, but it'll also be nice to beat up on some stangs in the area too lol. And since i always favor the under dog I believe i'll stick with the lt1 and since i have to do the bottom end anyway, i'm probably just gonna do a 383 build since they've become much more affordable and the le2 setup and call it goods. Cause no matter what i do if and when i beat her she's probably gonna step up to heads/cam too lol, but i guess i'd rather loose to my woman rather than get yelled at for blowing all my money on motor parts , come spring time i should have it all done a put together with some results, thanks for the input guys

I witnessed a full bolt-on M6 2002 SS dyno 363 and like 350 in the TQ range at the Fbody Rally in Atlanta back in 2004. 241 heads with LS6 intake, ewp, udp, cutout through QTP longtubes and other things. Car was dynotuned and guy was in my club. It was the higest bolt on LS1 that I or numerous other Fbody addicts had seen (at the time). There were a number of 98-00 cars there with 224/224 cams making 370'ish peak with less bolt ons. Obviously with a better curve.

I think you need to do more research. Most cheap 383 kits have cheap parts. Reason why you get what you pay for. Do a solid 350-355 rebuild with h/c and you'll be destroying your wife's car; assuming your trans is up to it and your rear end. Honestly to do a full build and not blow up something else your going to need more than 3k.

What mods are done doesn't tell the story. QUALITY of mods is a HUGE part of the puzzle. I have beaten multiple sprayed bolton LS1s with my stock shortblock NA heads/cam LT1 in a b-body.
If you think the displacement is the important factor then save yourself the trouble and let the old ladies car walk on you.

Just put down 1k-1200 get a LQ4 LQ9 do the swap and walk a whole bunch more than ur girl. Do some mods and u may have some coin left for dinner. SWAP IT! i did and i LOVE IT!!!!!!

I don't know about doing the lq swap.....does my tranny bolt up to that?, gotta replace computer and wiring harness? bunch of headaches to make all my gauges and components work right? and isn't the lq9 only rated at 345 to the crank?, what was your total cost for doing your lq swap and what was your horse power gain?......I enjoy doing different but for the money i'm thinking the le h/c with bolt ons is the way to go, but at the same time if any of you have a build price to do the lq9 swap that puts atleast 350-60 ish to the ground for around the same price as the le2 setup i'm game........
