Remember kids, too much horsepower is just enough.

Awesome and NOT an LS

That's a lot of grunt right there. Should be just about right!

I think those typically dyno 550-600 to the tire. With instant torque. I'd like to drive something like that just to see what it's really like. I figure I'm making an easy 700 flywheel hp with the turbo 5.3, but it's just different to the brutality of N/A power.

Really cool motor, gonna be a real fun ride for sure!

[Grumpy old man]

Yep it's cool ,BUT what are your plans for the frame to handle 3x the HP it was designed to handle ?

We have that exact same motor in a 69 camaro. Recently did a holley efi. Changed intake to a holley efi intake, running waiste fire coils vs a distributor (i looks like distributor but coils are mounted in back) and tuned on e85 made 630rwhp through a tko600. Thats around 750-775 at flywheel. The intake i feel made a huge difference. Btw it revs like a ls motor now.very fun to drive now and doesnt have any slow responce like it didnt with the dominator 1150 carb.either way, way more power than anyone every needs on the street and will shred the tires in all 5 gears easily

that looks like crap i will pm you my address and you can send that piece of junk to me and i will send you a slightly use sbc that will fit right in there and look way better. lol
nice very nice!!

Well, at a point this engine was not part of any plan. I came across a deal I couldn't refuse, originally I thought perhaps going with a 502 but I paid far less for this beast than I would have for the engine I was looking at.

Now, in regards to power vs frame strength...that certainly ran through my head! As the title says "over kill" there are few trucks out there with the set up to stick that HP to the ground without some heavy mods? My unit won't see a track and a good majority of those ponies are going to end up as smoke coming from the rear.

Now, with that being said...how many trucks on here have hooked up this kind of power and had frame issues? What are you running, what were your issues?

I'm at a stage to address these issues and welcome the constructive advice. But man, I can't wait to hit the gas on this thing!

Front view

[Teninchbluff]

Header clearance tight on this side, will have to address.

[Grumpy old man]

Chevy twist is an issue with a mildly built 350 ,Turn that monster loose and your gonna have a pretzel for a frame . I'd be thinking some frame boxing and a X member .You gotta remember it's sitting in a 50 year old rivited frame that probably worked for a living when new .Do the frame measurements X out now ?

[Already Gone]

I'd like to get a 72 Suburban and have completely stock looking with that engine up front.
