Eric I agree specially with the part about oil leaks.

Re: Pops 72 cheyenne dropmember build

Sounds like you're the guys to talk to, I just put a new Dart SHP sbc the rear main leaked immediately from your comments it sounds like I shouldn't try to fix it. Just a Quarters size when shut down, very disappointed, a leaky beast was one of the goals to get rid of.
I'll live with it for a long while, I'm broke now, but always planning for the future...that part is free

From Wikipedia, the free encyclopedia

The GM LS engine family is an engine design intended as the only V-8 engine used in General Motors' line of rear-wheel-drive cars and trucks. The LS series was a "clean sheet" design with little in common with the classic Chevrolet small block V8. Some LS engines are all-aluminium, especially the performance oriented engines, while others are cast iron, and all LS engines have 6-bolt main bearing caps.

The LS engine has been the sole powerplant of the Chevrolet Corvette since 1997 and has seen use in a wide variety of other General Motors vehicles, ranging from sport coupes to full size trucks. Due to the engine's relatively compact external dimensions compared to its displacement and power output, the engine family is also a popular choice for kit cars, hot rods, buggies, and even light aircraft.

Totally agree with you. I love the look of a stock big block under the hood or a small block for that matter. But I have had my share of valve cover leaks and carb. problems to last me forever. IMHO, a total stock engine under the hood looks way better but for driveablilty the LS is the only way to go. I plan on driving the blank out of mine too that is why I chose to go LS too.

Re: Pops 72 cheyenne dropmember build

i do agree that the LS is a better engine and i plan on driving mine alot also, and i know it is crazy to say as modified as my truck is i just want the motor to resemble the stock look, i hope i am happy the Throttle body injection i think that it will be a very dependable set up just not a hot rod....surely there is some way to stop the leaks ??

Re: Pops 72 cheyenne dropmember build

Thanks guys..so how different do they look under then hood from a big/small block? it seems that that is bit of a concern for all those considering the swap.

Just had a look in the wiki article...I now see why, they just look like any modern engine.

Re: Pops 72 cheyenne dropmember build

Mike I have heard positive and negatives on the throttle body injection kits that are out on the market. I am not sure they are worth the money. My truck fires every time and it is carberated. I don't think you will see that much better gas mileage ether. I have had a few friends put the self gunning throttle body's on there small blocks and they had a hell of a time running them. Not trying to sway you just letting you know.

Thanks Eric, always good to get experienced info. This is my first hp experience, so the $/gal is fine right now. But I can see it being an issue down the road. Two pals are running the FAST systems their happy (sbc and bbc) both mid 400 hp, but like yours key, two pumps and she fires every time. Good luck with the truck, this truck has one of the best looking LS motors.

What a difference from the LS in that Camaro that I posted earlier...it just looks like a stock V8.

i am using the factory tbi set up basically i have changed the intake and am using the bigger Holley throttle body other than that it is all of the stock components and those were pretty much problem free so i dont expect to have any issues there , like i said dont get me wrong i love the LS motors just prefer the look of the original....LOL i am sure after having my truck done a few years it will probably get an LS upgrade, but for now and for the overall look i am trying to achieve i just like the 350

Re: Pops 72 cheyenne dropmember build

Congrats Eric, I didn't think it would be too long for the mags to pick it up.

I also love the 1st gen motors, had long talks with a buddy that builds at your level, but I couldn't spend over $10g's to get over 500hp.

Your truck will look awesome with a LS motor, which version would you get, any power adders? The E-Rod came out after I ordered my motor, it had me second guessing my choice...or a truck 6.0l with a Magnaflow blower, gotta go by another lotto ticket. Guess the '40 is on the front burner now??? Keep us in the loop.
