If you are truly limited by a tight buget, You would be better off doing a weekend swap with a GM Gen 1 crate motor like this, it would have you back on the road in no time and give you a nice setup between HP and fuel mileage

http://www.jegs.com/i/Chevrolet-Perf...oductId=749882

Or any on of these that fit into your budget,

Speaking from experience you will be better off cost wise to do a GM crate motor swap, this would be a new motor, Not a used high milage LS that may give you trouble sooner than you would think.

Sorry but the ZZ383...a BUILT sbc is a 425 horse motor. A stock LS with a tune is in the same ballpark. Add just a cam,nothing else just a cam and you get more power better gas mileage and more realibilty than that 383. It's ok to hate an LS because you spent your money elsewhere but let's be honest about it.

Actually I have a cloned zz430 and it runs strong as steel. I do not think a 345hp ls motor stands a chance. My cost was easily less then a conversion before time and aggravation is added with modifications , and if i had to sell my car i would have a much bigger pool of buyers to do so.

Fridge AND freezer is fully stocked at all times. TEC grill fires up nightly. Can't help ya on the neighbor, but UCF is 10 minutes away...largest undergrad population in the nation. I'd say your odds are VERY good for nightly extracurricular activities.

Have you considered an LQ instead of LS? Same motor basically just out of a truck instead of car. Much cheaper also. There would be accy. drive expense and the intake is different but I have seen LQ motors for under 1k with the computer and harness. If you go LS why stop at a 5.3. Go all out and find a 7.4 and tell her the car is now yours Seriously you might want to check out the truck version of the LS just for a cost comparison.



BTW Junkman and UCF cant be a good combo. Too many storys for him to tell in the future. But I guess if he takes some pics fo us then all is good.

I don't think that I will get anywhere with USF girls once they find out I'm from Louisville. We're in the same college conference and Louisville has been handing USF their ass over the last few years!

I like Your thoughts too.
LQ engine is an Underdog, Sleeper.

7.4 - 454. Why stop there ?

Go to your local U- Haul center.
Open the hood on a late 1990's- 2000's GMC Gasoline rental.
8.1 L BBC V8.
I sometimes see these U- Haul trucks in the Boneyard.
Some negotiating may land a great deal also. 4L80E trans.
Swap Cam, Headers, lots of torque & Hp & break the C3 Rear diff or half shafts that are left stock yet.

454 LSX will make just as much power as a 454 BBC and do it with 1/2 the weight and 10x the mpg

Yes.
I am not 100 % up on all LS engines.
I know You can make over 900 HP at the flywheel normally aspirated with LSX engines with GM Motorsports & Brodix & Trickflow Heads.
Pretty costly though.

496 BBC is a good engine too.
8.1 is actually a 494ci.

I would try & keep costs down for now.
Up to him.

A friend of mine has a 1979 Corvette Shortblock in his machine shop. Passed magnuflux test. Stock bore. Owner left it 5 years ago & never came back. 010 block.
Common scenario in machine shops nationwide.
Recession came & no one came back or calls again.
Finished & unfinished engines.

BBC was never light.
Built right its a driveline destroyer with weak trans & diffs.
Everything working, it still wins many races.
Dragstrips prove that nationwide.
