Cant really find anything on a search. Trying to find a performance oil pan to use under a gen 1 small block in an LT1 car with longtube headers. It's a 2 pc rear main so cant use a late model pan.

I know there's guys out here who've done it. What pan do you run?

 

i would imagine a standard sbc pan would work fine....

 

So did I, but if you look, there's a big difference in older pans the way it angles down toward the sump. I'm expecting there to be some interference between the k-member and the pan. And alot of these pans that have kickouts look to be so wide that I see header interference a problem. So I'd rather be sure before handing out the cash on a pan that might not work.

I already have to modify the pan as it is for the low oil level sensor. Yeah Im doing that crazy 400+ ci LT1 injected mod. I'd rather start with the right pan in the first place, so I dont want to get a cheapo ebay special.

 

get a tubular k-member.

 

I have to! Never tried it, but from what I see LT1's will bolt into earlier motor mounts, but not the other way. Why I dont know. So i have to assume a 400 SBC will not bolt into an LT1 engine bay without some modification. I plan on using the UMI K-member since it's a reinforced piece.

But again, I want to make sure there are no interference issues. This thing will be swinging a 4" crank.

 

it will bolt in. i unbolted a sbc from my gta, swapped the mounts onto an LT1, and then dropped the LT1 in.

 

I just did the same thing, took out my LT1 and dropped in a gen I small block. the standard oil pan fit fine, the motor mounts will work, but you can only use 2 bolts per side. so I also put a front motor plate on mine to help reinforce it.

 

Well that's a relief... kind of.

I know the LT1 uses 2 bolts per side. And I dropped the LT1 into my '86 without any issues whatsoever. My concern is 2 bolts instead of 3... the motor mounts on the block are triangulated for strength. I will get a k-member either way, but that this tells me is that the k-member for a standard sbc in an LT1 car will also work for an LT1 with standard motor mounts.

Of course I have a welder and a torch... so I can make one of the many sets of motor mounts I have work for the time being.

Im assuming the oil pan you're referring to was a gen 1 in an LT1 car with the stock k-member?

 

An LT1 in a third gen, and a SBC in a fourth gen, chuckle.

 

i have an LS1 in my LT1 car, and an LT1 in my TPI car.
lol....

 

Use an 85 earlier SBC pan designed for a third gen chasis, it will fit the stock K member of the LT1 car, but I would get the tubular K just to have the mounts made for the SBC.

On an LT1 the mount bolt holes on the sides of the block are all there but on the passengers side of the block there is an extra hole for the LT1 f-body motor mount.

The traditional SBC can use the LT1 mounts, but it will only have the holes for 2 bolts on the pass side.

 

LOL Aint that the truth. Well I had a TPI motor but it needed alot of work and it is honestly outdated equipment. I dont wanna drop in 2 grand to rebuild a motor that was a 305 and needed injectors and a league of machine work, pistons, new v-belts, etc...

Especially, going from a thirdgen to a fourthgen, back to a thirdgen... performancewise, what was the point? Mods cost more (intake, mostly), the nose is heavier, brakes are smaller... but I liked the body style of the IROC's and GTA's. So I figured I'd 'update' one. So I decided I'll build a big cube sbc for tons of power for my built car without the revs (hardly rev it over 4000 anyway), and put the 383 in my TPI car to replace the 350 it has now. I have a cc305 (good TPI cam for a 383 and the compression is about 10:1, which would make an awesome LTR 'TPI' motor. Tons of low end torque. Now it just needs a supercharger

I have a non-bastardized 89 350 TPI GTA, so that'll be the car I wont mess around with. Unless I cant find something else to drop an LS1 into

 

That's what Im talkin 'bout! haha
Good stuff to know. Im on ebay lookin at pans now. Thing that's gonna suck is that no matter how nice the finish, I gotta screw it up to add the hole for the low oil level sensor.

*EDIT*
Are you sure all pans will clear the LT1? Reason Im saying is the stock pans look like they'll be ok, but I was looking at a canton for a pre-'80 block and it's awfully deep in the front compared to the LT1 pans.

 

M yfriend is doing the same thing. SBC into 4th gen. What headers are you running? We want to put LTs but will lt1 longtubes bolt to stock TPI heads

 

Why not leave the sensor out? I'm pretty sure you can just splice the wires together, and you won't get a 'low oil' light. Just a thought.
