Thanks I would appreciate it. Here is a link to my build I haven't really gotten into the swap part of it just the engine building. https://ls1tech.com/forums/carburete...-370-swap.html
I will probably have a few more questions for you before I'm done haha

This is what i used to get to the nuts on the motor mounts. Its a lil harder on the passenger side cause of the top bolt that's all the way up their. Your gonna have to have some patience for that bolt. Your also gonna need some one else to get a ratchet or a air gun and take of the bolt while you hold the nut.







These are the passenger side nuts a lil less space than the drivers side as you can see.



And these are the driver nuts, more space and easier to see the nuts. This side is the easy side shouldn't take that much.

Well this morning I couldn't wait, I just wanted to see if my clutch will fit with the flywheel. And good news it fits! Just needed to push out the pins on the flywheel and it worked like a charm.

Well today is a sad day. I tried getting flywheel bolts here locally and noone had them. So i am going to order the flywheel bolts and pressure plate bolts this Monday. Hopefully they get here soon.

You're gonna need an external regulator or the corvettes filter.

Did you have the headers on before you put the bolts through the clamshells? If you leave the headers off until after the bolts are easy to get in, even with 1" setback plates. I've done 4 obs swaps and never had to spend more than a few minutes on those bolts, and the Shoenfelds will go on after the engine's in place. So will shorties and stock manifolds. Nice build by the way, I'm doing a 92 sport right now, LM7/4l60e swap.

And all 4 the old P/S lines went on the new pump without issue. What's your plan for a fuel pump?

91ls1silverado

Yeah I know. I'm going to get a Corvette Fuel Filter Regulator.

What do you mean by clamshells? motor mounts? I put the headers on after I put the bolt in the motor mount, was pretty easy!. Thanks and nice!!

91ls1silverado

Nice thanks for the info! And this is the fuel pump i am planning on getting.http://www.highflowfuel.com/i-478352...1988-1995.html

Well, just ordered arp pressure plate bolts and chevy performance flywheel bolts. Arp bolts get here the 16th and the flywheel bolts don't ship til the 17th, just my luck. Well that isn't going to stop me, going to do my fuel setup and clean up the engine bay this weekend.

How do i run my fuel lines? I'm a lil confused on that part any info or pics would help thanks.

Great looking swap, My friend is in a search for a 90s single cab to swap out his ls1 and 4l60 out of his Camaro soon. This will help us out when the time comes, Thanks

The lines from your 1992 truck work with the ls power steering pump.

Do it man, the engine fits perfect in the engine bay, more space to work with than the 350.

I am going to try to put my trucks stock power steering, and the pulleys are the same, so thats a big relief.
