Thread: crate blocks

Tweet

There are many different configurations of Goodwrench engines available, including an L31 with OE roller cam and Vortec heads at about $2200.00 - but it is a two bolt main block with, I think, cast crank, rods, and pistons.

If your planning to add Vortec heads to the $1700 Goodwrench engine, the swap will run you 500 - 600+ with a valve spring upgrade to run a decent cam, plus the cost of swapping to a decent cam.

For the money I still think you are better off going with the 330hp GMPP 350HO long block as it already has the Vortec heads, a 4 bolt main block with high nodular crank, PM rods, a performance cam, and better valve springs at under 2400.00. Bumping it up to 350hp or more should be relatively easy with just a hydraulic roller cam swap. I just don't see how you can beat this deal and you can use the accessories from your old engine.
