Post Anyone swapped in a standard sbc for an LT1?

Yes, it's been done and you will probably get some responses from those who have done it. If you do a search you will find some threads where this has been recently discussed.

I considered this at one time and rejected the idea, deciding it only made sense for a race car. If that's what you are building, it may make sense since it enables you to use aftermarket blocks and all of the other Gen I SBC stuff, especially heads. But keep in mind that everything will need to be replaced from the diff forward.

When you consider that the 4th gen is poor platform for a race car and that you are talking about a complete new drivetrain it's hard for me to think this is logical even for a race car. I am going to start with a totally different platform and build a "real" race car, keeping the Z-28 for what it's good (great) at: a fast street/strip car.

What do have in mind? If you are building a race car, what class will you compete in?

I also share your thoughts that this would only be good for a true race car. I also know that the f body platform would make a poor race car in a extremely high horsepower application and have been thinking of going to a professionally built race car or possiblly a older car with a more rigid chassis. The class that I am thinking of running is the pro stock class in the PRO/Edelbrock drag racing series. It is a NA class for 1950 and up cars and trucks and you have to use a stock configured suspension. I may just race my car the way it is, then later sell it and build a real race car from the ground up. Thanks for the response rich.

Thats a carb'd only class by the way RJE so keep that in mind.

I'm going this route but I changed just about everything on my car. Not a daily driver setup by any stretch of the imagination but if your building a "fun" car that doubles as weekend fun and strip warrior then I wouldn't hesitate cause there are definitely more options to pick up the pace down the 1320...

I will be going to a aftermarket block setup myself... I cant wait to have one so I can really lean on my car Shouldnt be that hard to do. I am already running a crab style crank trigger setup (well have and will fit) but besides that not that hard.

Thumbs up

Yes, everything will need to be replaced.
I've dropped Motown427 carbed sbc with full
sized H.E.I. Cranktrigger would be alot less
complicating to deal with though.
Alot of things are needed to do swap.
I went with a PA K-member.
I really think that it(standard small block)
will not fit with out it.
I also made motor mounts.They need to be shimmed up off k-member for oil pan to steering rack clearence.
The driver side motor mounts will work with minor fabrication.
Cowling at base of windsheild will need to be cut back to glass for ease of install and
room for carb.
Radiator will need to be changed. With minor fab work a 69 big block rad will work.
Local shop in MI(Superior Radiator)in Mt Clemens MI Built in one day $400.
Lt1 hooker lt headers fit.
For engine combo 17/8 headers are needed
Headman hustlers Make them for lt1 car. $525
bare.
I just did this to 94 T/A
If you want to stay E.F.I you can. F.A.S.T,accell,and a few other companies offer trick set ups for converting to efi
E-mail me if you want more info at

thanks
