The issues with putting in a SBC into an LT1/4 car are far more than just pulleys and the things you mentioned. How do you plan to interface with the cars computer? The computer drives the instruments so not interfacing will create the need for new instrumentation, etc etc etc.

It would be far more cost effective to:
1) rebuild your existing engine (the lt series engine is not problematic) or,
2) if you want to swap to something else, consider an LS engine. You can get a computer that will run the engine, the transmission and the gauges.

Of course, it's your car and you can do anything you want, but I'd think you could get a hell of a LS setup for what you'd end up spending to make that SBC work.

Good luck whatever you choose to do...

its an lt1 ,I am not worried about computer its going to carberation ,I already got the motor I wastoldbye a pretty big perfromqance company an the mech it will go in an not that much money if you don't want answer my question about the pulleys an try to talk me into something else then see ya this site is for what isee how old some of the threads are

guest106319

well I am not a pro but was hopeing to get one the computer will stay in the car to run the things it needs an wires will be capped off that are not needed an ls1 motor has less power an cost a lot more ,an fuel system taped into that's what the fuel regulater is for ,my mech has done it before or he would not have suggested a crate motor ,if the luuley don't worh then I get set that does I just wanted few simple question answered my mech can figure out the rest ,

Ok, what specifically do you want to know about the pulleys? You can get lots of help here if you can narrow done what you're after....

guest106319

seems the only one needs to work is the underdrive pulley from the lt1 there ,the others will trouble shoot to place corerrecltly,there both 3 bolt pattern I plan on using same alernator new one old powerstreering an ac cpompresser,an the water pump from the lt1 if it possible it brand new ,thanks

guest106319

I am keeping a serpentine system

guest106319

400 small block 350 the bolt patterns should be the same ,it was karl performance told me the pulleys will work,an the waterpump the one that comes with it delete couse it turns other way ,as a matter of fact ,I ordered it with flex plate to fit the tranny flywheel,an no pulleys at all an no water pump couse I can reuse mine was what I was told ,it was an exchange the flex plate balanced ,

whats new with forums like this 37 looks an one guy post no help .that ok I don't need this forums help probely mislead me anyhow ,you all that just read aaahhhhh

If the new engine is an LT1 (like you say in post #3), then everything you have will work on it.
I'd consider trying to be more clear and dropping the attitude if you want help. Waiting only a few hours, then dissing the forum is no way to make friends.

Suggestions:

Type your questions in clear English. Right now, they are virtually unintelligible, which may explain why so few people are trying to answer.

Be patient. No one has an obligation to answer your questions immediately. If you can't be patient, you might want to consider another site.

As noted above, lose the attitude. You are posting on an LT1 engine forum. Why are you surprised that people choose to emphasize the benefits and potential of the LT1, rather than a somewhat antiquated carbed Gen 1 SBC? When someone did try to help you, you insulted him, because you weren't happy with his answer. Might explain why not a lot of others are trying to help you.

If you think a 364HP Gen 1 SBC is more powerful than an LT1 or an LS1, you simply don't know what you are talking about. Numerous people on this site have 500 (flywheel) HP stock displacement, stock bottom end LT1's. Get the stock LT1 heads ported by someone who knows the LT1, and you have a damn good engine, at very low cost. LS1's can support 600HP without breaking a sweat.

Why are you asking about an "underdrive pulley"? With all that Gen 1 SBC HP, and torque, why do you want to run an U/D pulley? One problem with using even the stock LT1 pulley would be that the typical Gen 1 SBC has a damper with an external balance weight on it, and the LT1 pulley, which is integrated with the harmonic damper, is neutral balanced. You would have to check to see how Karl balances their engines.

And to answer the question you asked in the other post you made, no, you cannot use an LT1 water pump on a Gen 1 SBC. While 90% of the Gen 2 LT1 is identical to the Gen 1 block, the front of the block is totally different, with a unique "reverse flow" cooling system, and a front distributor mount. The LT1 water pump is also driven off the cam timing sprocket.... no way to make that work on a Gen 1 SBC.

Since you are so unhappy with us, you can be removed from the site. In plain English - you will be "banned" unless you clean up your act.
