carbed small block conversion

Im swapping the lt1 to a carbed 400sbc. Does anyone know anything about this kind of swap and if so what do i need to modify? The distributor seems like it would be just about impossible to get to and the carb and air cleaner might stick to high. thanks

MSD makes a low profile distributor and you can get a drop-base air filter, not sure how makes it, maybe mr. gasket. Not sure if they'll work, but worth looking into. You could always get a cowl-hood to give you plenty of air filter clearance.

Personally, I've had enough of carbs, I'd keep the LT1...but that's just me.

good luck and welcome to the site.

That is correct the standard distributor cap will hit. As stated above the low profile distributor cap (crab cap) is made by many manufacturers. It does provide more room. But if you would need to pull the distributor you will have to do some cutting!! The air cleaner is also an issue as stated above. You can notch the cowl and run a cowl induction hood for added clearance. The other issue is the fuel system. The LT1 fuel system is designed for 41-45 PSI of fuel pressure. So that intank pump and fuel lines will have to go! You will only need aprox 6-7 PSI of fuel pressure. So a holley blue and some fuel lines and fittings. If you are going to street drive this car then you can adapt to the stock fuel tank for suction. Its not a bad swap, Id keep the LT1 for many reasons!!! Good Luck on your project
