Going with A JASPER 355
Going with A JASPER 355 Im going to be picking up a Jasper 355, for $1,100...
Its got 2k miles on it, big improvement from my 140k stock LT1..
Jasper says it comes with 333hp/375tq and Im already full bolt on's... So Im thinkin bout either going with the Hotcam kit or just gettin a cutom grind from L.E.
I would like to put down over 350rwhp with this cam only 355...
What are your thoughts?

I've got a hotcam for sale, $100 shipped. It has one flaw, but it is on the backside of the ramp so it shouldn't matter. (My engine builder looked at all my lifters twice, all still smooth.)
I had a Jasper reman in my 83 Z28. That 350 took all the abuse I threw at it.

Those HP numbers they gave you are engine dyno numbers so they are better than you would see with accessories and full exhaust and all. Hell they are lower than I would expect from a completely stock LT1 tested the same way.
You are buying a bottom of the barrel reman engine, I would sooner use a junkyard engine if looking for a performance base to build on.
The ONLY thing a company like Jasper has going for them is offering warranty on commuter car engines, I might consider them for a new engine in the wife;s car just to get warranty but never would I consider them for something I was going to tinker with and void the warranty or expect performance from.

I wouldn't bet on that. What's wrong with your 140k LT1? If it has no major issues right now, it will probably end up outlasting that Jasper engine.
......if i just wouldnt have started chasing the dog in it after i drank to many beers and forgot to turn the fans on.....itd probably still have the stock motor in it.

I live about 60 miles from Jasper. I used to live even closer and had friends that worked there. They said they make make descent engines for your daily driver but not for anything you want to beat on. This was about 10 years ago so I don't know if anything has changed.

Used to live closer, huh? I grew up in the grand metropolis of St. Anthony, about 10 miles from Jasper, along SR64 toward Clarksville.
have a jasper in both my camaro and my 93 f150. while i did not replace the motors the previous owners did i have no problems with any of them. and i beat the living crap out of the ford. every problem i have had was because of human error by the installer
