LS heads on a 350 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Jstock85 · 01-06-2017, 10:42 AM

Got a compatibility question concerning an engine. Will the heads from a 4.8 or 5.3 LS fit on a 350?

Thank
Jeff

Not even close. Only 350 they will go on is an LS1.

Pricey, but if you really want, you could get one of these blocks, http://www.theengineshop.com/product...ron-block.html

Vortec heads would be a nice upgrade.

The conversion block is a nice piece, but it does have its draw backs.

High port LS heads flow incredibly well, but the block cost mint.

Edelbrock Vortec heads are cheap enough, and can get some good HP too.

Myself I would just use a 6.0, and the msd ignition kit.

I don't get it. All that money to run LS heads? Why not just get some AFR's or even 18* heads instead?

Agreed, but there must be some out there who want it.
