LS to LT swap

[DKz Garage]

I have a DSE from sub (69 Camaro), I had an LS motor using DSEs engine stands and mounts along with a Bowler Trans x-member. Putting in an LT4 and wondered if I have to ditch all the LS mounts/stands from DSE and go with the Hooker/Holley system that was designed specifically for the LT engine?? Or, is there an adapter plate that mates the LT with the LS stands, etc..... I don't want to run into any drive-line any issues......

TIA for any input.

Im sure you know the LT is pretty darn the same DNA as a LS. Im confident all you need is the LT adapter plates to SBC mounts. Just like the LS. I think ICT has some.

That's good to hear...... I actually ordered the ITC plates yesterday.

All depends on your motor position in relation to all the systems working together. Get with DSE and ask since its their subframe, everyone else is just speculating. The LT blocks have their mounts more forward than the LS blocks but its not a huge deal with the adapter plates.

ICT plates have three mounting holes, factor SBC position, 1.625" forward and 2.25" forward from factory sbp location, at least these were what they used when I last checked. I've used these and had to go with 1.625" forward from factory and I have maybe an inch before the PS head hits the firewall on a stock subframe to achieve -3 degree angle. Not sure what you would use with the DSE subframe so ask them. Also, depending on where you put your motor will affect the headers slightly (also need LT specific headers), the trans mount if not adjustable and possibly front accessories/ intake tube. Maybe even the trans tunnel depending on if it was raised or not. Its an easy process just keep up the research and you will find the answers you are looking for. ICT billet has probably the cheapest and best looking PS add on btw (if it fits the DSE subframe).

And how would this be different than a LS swap?

You are spot on. I'm going through a similar build. Dropping an LT4 into an old F-Body. The Mounting points on the block of an LS and an LT4 are the same. Here's the difference I've noticed. Adapter plates for an LS. The threaded mounting points on the plates are much lower, almost parallel with the Adapter plate to Engine. On the LT4 plates. The threaded holes are quite high. 1/2-3/4 inch above the plate to engine mounts. Make sense ?

Now I'm tempted!!! I have the LS7 but....seeing how people are taking these 650hp LT4s and doing some minor mods and making 800hp is insane!!

Alright everyone settle down , you would know if he was a moderator because it would say so in his profile . Having said that everyone is allowed to have an opinion and no one has to agree with it . Let's all try to not take thing so personal and remember why were all here
