Chevy LS Engine Question

Postby Bucky » Sun May 20, 2018 2:57 pm

So a buddy of mine (Ford Lover :roll: ) tells me that the LS Chevy engines were designed by Ford many years ago and sold to Chevy. Is there any truth to this.

The LS engines replaced the LT motors and were considered a brand new design when they came out around 95 or so. They didn't share much with their predecessor LT. Never heard anything about a Ford connection with them. They did change the firing pattern to match the Ford, but other engines used that same firing pattern also.

I guess that's why so many guys with mustangs put LS engines in them other than they want to go fast....

I find it surprising that nobody even seems to recall the original Chevy LS engines made in the 60's and 70's. The most popular being the LS6 454 that was mostly found in 70 and 71 Chevelles. They had forged cranks, rods and pistons, solid lifter cams, large valve rectangular port heads and 4 barrel aluminum intakes. Power was rated at 450 HP and 500 ft-lbs torque. There was a LS7 version of the same engine that had higher compression and maybe a larger cam (think it was the same cam that came with the high performance (L88) 427's).

I bought one of the LS6 454's around 1990 new in the crate from a local Chevy dealer. Anytime I mention having it, most people now think it's one of the late model engines that is a totally different animal.
