Jasper Long Block opinions please
I spoke to a Jasper Engine representative and they will rebuild my engine for $2,100 for a long block. The engine comes with SR torquer heads, Hyper pistons, moly rings, a dual pattern cam similar to the XE256 and a steel crank. They advertise 300hp and 365 LB Torque. I didn't think that was bad for the price and also has a 3yr 75k mile warranty. All this was standard except the steel crank which was $150 more. Any thoughts? They'll also do a short block for $1,400 which isn't a bad deal either. Any body use Jasper before?

I think your going to regret getting only 300 hp., I would really shoot for 350 to 400 ponnies or more. I would check to see how much more it would be to bump it some.

GM's HO 350 is about $90 more - has 330 hp and 380 ft lb of torque. Warrentee is shorter. see Salee chevy's link http://www.sallee-chevrolet.com/Chev...ckV8s/330.html
warrantee is only a year though
sounds like the jasper engine is right in there

Re: Jasper Long Block opinions please (Tominator)
Your probably right and A friend of mine says the same thing. I could always get the short block for $1,400 and put my own cam(XE262) and heads(sportmanII). Its just theres only a limited warranty then just on parts. I also thought the 360 pounds of torque would make real streetable engine.

Re: Jasper Long Block opinions please (fauxrs)
Yeah I really like that motor but the cast pistons and very expensive intake made me look elsewhere. I've always heard not to use cast alum with more then 300hp. Not that I could tell you why.

Re: Jasper Long Block opinions please (TTop Tony)
I'm probably beating a dead horse here but I would try to get enough ponnies under the hood to beat a stock Z28 on the street. :yesnod:
I guess what I'm saying is that after you drop the coin for a motor, I wouldn't want to be intimated by a stock Z28/SS or Mustang GT/Cobra street light to street light. I not endorsing street racing :crazy: but it happens (at least in my dreams).
Build to enjoy, not to regret. :D

Remember Penny Wise, Pound Foolish. Don't short yourself. On a project like this the hardest part is doing the work. If you are going to spend $2000+ for a crate engine, spend the little extra and get something you'll be happy with for a long time. If you don't you'll kick yourself in the rear for a long time.
There isn't anything wrong with the Jasper setup but, I know if you are like most of us car geeks, you'll always wish you had more POWER! Get enough to wake yourself up.

Re: Jasper Long Block opinions please (Smokehouse69)
Yeah I know. Thats kind of why I put this out. I needed some reinforcement. I was thinking I can always upgrade when the warranty runs out. But your right thats stupid I should do it once and do it right.

Re: Jasper Long Block opinions please (TTop Tony)
Jasper offers quite a range of motors, I went with one that puts out about 325 hp, but since I am adding tpi, it should bump that a bit.

Re: Jasper Long Block opinions please (TTop Tony)
Somebody in here posted a co selling complete rebuilt 427's on ebay for about the same money.
Maybe this only makes the decision more difficult.

Re: Jasper Long Block opinions please (TTop Tony)
Jasper rebuilt my 350. I think they call it a class 3 which is a 350 horse engine. If I had to do it over again I wouldnt. But not because of anything Jasper did per se. I wanted a car that was quick from 0 to 60 and could care less about top end. What I got with their engine was just the opposite. Slow off the line and hell bent for leather after 3000 rpm. It has a 292 duration cam which is tough on vacuum and old vettes need all they can get. I have a TH 400 with shift kit which helps a little but a manual tranny would be much better with this setup. In the mean time I need to change torque converter and jets in the carb and maybe a different setup on distributor to make this car run the way it should. I'm also getting ready to pull the heads due to a little smoke on startup and a badly fowled plug. A waranty mechanic for Jasper told me they had some bad valve seals in the heads, but of course when I learned about it my warranty was up. Jaspers web page should have the data on this engine.
I used to work for a large contracting company and they used Jasper engines and trannys and we never had any problems which is why I let my now disapeared mechanic talk me into this engine.
Hope this helps.

Hey Tony:
We have a Jasper long block in the car. Had it put in last March. Previous owner killed the car. Let's call it a Corvette Rescue. Never give a lawyer a vette. Don't have a clue.....
Our mechanic told us about Jasper and the warranty is what sold us. 3 year 70,000 miles. It is a 350 I do believe it is 220 hsp. It is a great motor. Makes the previous owner green :cry with envy, he sees the car all over the place. In parades in our small town along with our car club. We have had zero problems with the car. :D
We finally have 5000 miles on the engine and I went to pure synthetic oil. That made a difference as well. Car runs cooler and I drive it 500 miles a week to and from work and with the wife on the activities committee the car is going non stop. :reddevil
Just my opinion. Never been happier. Glad our mechanic talked us into the new motor. I have taken on a couple " tangs " and waved Bye Bye as I went flying past them.
:cool:

Re: Jasper Long Block opinions please (Mr. Bob)
Sounds like Jasper is worth looking into. I too am looking for a lot of low end torque even with my 4 speed. I drive my car mostly on windy back roads and deserted highways. Also I do have to pass a sniffer test. It pretty tame for 1975's but I don't thing a 427 would work for me. Besides since I think its the original motor I'd like to use it. I just started tearing the motor down if you'd like I'll keep everyone posted. If my motor held out I was going to put SR Torquer heads and a XE256 in it anyway. Which is almost exactly what they use.
