<---------If you WERE GOING TO DO IT ALL OVER AGAIN-------------> Wanting to do H+C+I on my otherwise stock bolt on 2000 TA M6 with 120,000 miles on the clock. With that being said I know that the engine isn't going to last forever, its healthy at the moment runs great no oil consumption issues at all etc…
I check this forum regularly to change my wish list before I pull the trigger, just getting out of college so I want this to a awesome build. Debated all of different heads/cam options and combos on this forum. Been waiting quite a few years for the chance/income to do my dream build. Im the type of guy that would rather wait and plan out my build perfectly instead of rushing in a changing parts later down the road.
Here's my concern the Thompson/Texas Speed/ +other suppliers short blocks looks really awesome for the price. Would you start with a brand new foundation (short block) or just use the stock ls1 120k, in my car at the moment. I know most heads are designed around the engine bore and stroke which is my main concern, CC, chamber volume size etc... I really don't want to buy badas* cylinder heads twice, or leave a lot of hp on the table, when switching to extra cubes. I would most likely go the 402 or 408 route in the future. Budget won't be a huge concern have a great job lined up after graduation.
All help and advise will be greatly appreciated, this is a great community on here. Explore some different options and routes if you were going to do it all over again.

I'd leave the shortblock alone for now if it is still in good shape and get the best heads I could and do a head/cam swap. Then when the short block goes you can increase your cubes and still use the heads.

This is just going to be a weekend warrior type of build that sees the track a few times out of the year.

Yea I have thought about these types of builds. Not sure if I am skilled enough for a turbo build at the moment lol to be honest. Long tubes are already installed as well as true duals. I really wanted to do all the work myself with this one.
if i had to do it all over again the only mistake i made was going with too small a cam. (ls6 / i dont do my own motor work) i wanted a fun daily driver with great street manors and nothing objectionable if i needed to sell. that said if a pile of money landed on my lap i would think about a bigger motor with good street manors of coarse. you should look at the book dyno proven perfomance to get some ideas (sure its one big advertisement) in that book the ati super charger catches my eye. i would lean towards an aluminum 454. cheers , goodluck!

get a shortblock and build it on the side. when you're ready, pull the ls1 out and sell it.
dollar for dollar, your money is better spent on F/I if you care about power but then again there's something to be said for n/a power delivery.
if i had to do it again, i'd probably still do n/a but would probably add more cubes. honestly though a 347 is probably all I will need in a 3000 lb car.

I have had max effort h/c/i 346 and now I have a forged 347 that I'm putting a blower on.
If I had to do it again, I''d go 416 LS3 from the start and badass heads shooting for 525-550 rwhp N/A. I'd leave the LS1 stock and I would sell it to offset the cost.
Why?
Because a 130 trap car is all you need on the street. Anything more than that is largely useless under triple digit speeds.
My old ls1 setup trapped 125 and even that was "almost" enough. You get used to any power anyway, and someone else out there is always faster regardless of how much power you make. There are 750 rwhp F/I guys who think their cars are slow lol.

If I could do it again I would have done 5.3 with a turbo when I put another stock longblock in a few years ago. Although Im happy with the car and intended on having a project/dd (which its been) id like more power just like every one else. Where Im at now, Im not sure if I just want to do heads and call it a day or slap on a shot of nitrous soon or save for a procharger in a few years.
Cars suck lol.

Old stock stuff breaks, like lifters & rod bearing failure.
Do it one time & make it reliable, the places that specialize in it have it figured out pretty well. IMHO I'd get a aluminum 5.3 block bore it, put in aftermarket rods & lifters and get a cam that's not really hard on parts.
You may not win any dyno shoot out but it'll run good & you won't be getting it fixed all the time.

Yea really, if I had to do it all over again I would have left this one stock and built something track only. That said I probably would have been satisfied with a stroked H/C 383 but somehow just had to have the big cube. Really as the other poster said 130 mph trap is just stupid on the street and it is rare to come up against anything that will give you a run.
