LS7 swap

**BULLET_WS6** · 05-19-2007, 11:14 PM

Ok i know people have mentioned COUNTLESS times that any ls series engine will go into any ls series cars using the same mounts, etc... it should slide right in...
But why have i neverrrr seen an ls7 swap... i have seen lots of ls2's, less commonly ls6's including one of my friends... and 0 ls7's... anyone know why?

the ls7 cost what $10k-11k motor wise, most people put $6k into a 402 or 408 ls2 stroked motor (small block, heads and cam) and get as much out of it as if they installed a 427ci ls7 motor. my 2 cents.

**BULLET_WS6** · 05-20-2007, 12:02 AM

yeah i can see that as a detterence... valid point.. but 500hp stock is no childs toy, i figured someoneee would have money to blow and do that
this is a question that i have no idea... if you put 12 grand into the install and modifying of a ls2 can you push 500 hp... and if so.. wouldnt it be nice to have the 500 hp "stock" but from what it sounds like you can probably get well more than 500 hp with that kind of money into a ls2 swap

I got 630hp at engine with $7-8k motor + supporting mods (full exhaust etc)... $4200 small block 402 stroker ls2, afr225 heads and g5x4 cam. it make lots more power than 530hp LS7 (it is underrated > 500hp)

**djvaly** · 05-20-2007, 12:09 AM

but yeah an LS7 should fit right in, but the wire harness is different and other things such as oil pump, etc etc...

**Mr. Luos** · 05-20-2007, 02:26 AM

The LS7 block will fit right in.
Now the dry sump won't. Wiring harness is similiar to the LS1, but changes would have to be made there as well.

The LS7 is a great motor, but the Corvette it is in really makes it fly. 440-450 at the wheels with a very flat torque curve is nice, but for less money, I will take my powerband with more power.

GMHTP already had coverage of a LS7 swap in a Camaro by GMPP. Honestly, I was less than impressed even if they did pick the wrong rear gears...
As Mr. Luos said, it is a pretty direct swap asides from the dry-sump oiling system. However, it isn't a very cost-effective swap at $13K plus installation. I make more power with my little $5K 383 and still have plenty of room to grow. If I had $13K to blow on an engine, it had better be putting down around 600rwhp.

The LS7 is a god in a 3100 pound Corvette.
It suddenly isn't all that fast when you drop it in a 3600 pound car.

Plus the cost. $14K for the motor...the car is probably worth that much, if not less.

I think the practicality of cost effectiveness kills the swap project.
perhaps us gear heads that know a thing or two of being cost effective and getting even better results makes it unpractical. but then again you get
a vette c6 or c6 owner (no pun intended) that throws $12k for LS7 swap. ok fine.

thanks for all of yalls input, and danziger, do you have a link so i can see that swap?

**slims00ls1z28** · 05-20-2007, 11:32 AM

Theres one there. Dry sump and price definately 2 biggest obsticles.

**BULLET_WS6** · 05-20-2007, 11:45 AM

im not gonna lie... thats a good article and the swap sounds badass... but yeah it would definitely be financially hard... if i win the lottery i will do it

**slims00ls1z28** · 05-20-2007, 02:07 PM

If I had money to burn I'd do it in a heartbeat. Dry sump oiling, 427 CI, Titanium rods. I'd change to forged pistons add Forced induction. and call it a day.

**BULLET_WS6** · 05-20-2007, 02:28 PM

indeed, and i would hafta say i would rather it be in a camaro, have my ls1 t/a on the side, style the ls7 camaro after a zl1

But by the time you change the pistons and cam for F/I, you could have built a monster dedicated F/I engine for less money. Hell, for $14K you could do a WarHawk block-based 454+ c.i. engine that would do 600rwhp N/A and hit it with a 200shot when you feel saucy... It's not that I don't like the LS7, it is just a under-achiever in factory tune. That's the price of a warranty I guess...

completely agreed... but this is more of a us saying if we had the money as in... enough to have what you just said and then a few ls7's if we want...

i completely agree with danziger and Luos on this one. i have that issue and read over it several times trying my darndest to figure out why they were hyping it soooo much.

the magazine only managed a 12 second e.t. but was having trans issues. i figured with the little modifications they had done(exhaust and slicks) it would go 11.60s. heres where the problems start for me.

11.60s in an ls7 equipped f body=sweet. but after the 12k or so youre spending on the crate ls7 you may not be able to eat the cost of a beefier drivetrain and superior suspension (youll need it for sure) to get it down the track safely and fast. im being generous here, assuming that it has headers and atleast a catback.

if you take a step back...11.60s in an f body is easily attainable for FAR less money. you could have 5 0r 6 grand and built everything to a T. that would cover heads and cam/tune/rear/exhaust. then if you had the other 5-6 to play with....any big cube build you want....any power adder you want...any assortment of trans, clutch,...you name it. and i guarantee you will be WAY faster than 11s.

11.60s is cake with the ls1. why would i spend 12k on something that will leave me with around the same times for 6 grand more and no money for mods?

i like the ls7, but not in an f body....too expensive at present.
