Summit Brand LS Blocks ?

[travmon]

Does any one have any info on these steel blocks 4.8 /5.3 for 399.00 with machine work done ?? Seems like a heck of a deal when I add up tearing one of ours down running it to the machine shop for freshening and then picking it back up..Time alone is a lot versus something that shows up for that kinda money and just needs a hot bubble bath , ck some tolerances and toss it together.. I would be interested in what foundry they are coming from...One of you big hitters should know someone that knows someone that slept with someones sister that now is married to a Summit Racing executive ?

Wondered this myself. I was placing an order a few years ago, and I asked my salesman if he knew who manufactured Summits gear sets, and he quickly told me that he had no idea. Probably the same with these blocks. I believe that these units even come with cam bearings installed, for this price.

They are unmachined blocks. I have already call on it and they actually changed the description because of my phone call about 6 weeks ago.

The web site says that it has finished cylinder bores.

but when you read dimensions, they are undersized unless they changed it again

My Summit description says "Factory Overstock" which I believe was an over-run of GM parts and bore is Finished 3.780 which is 4.8 or 5.3 liter finished bore size depending on which crank you drop in it. Woops the Summit on line description says "Summit brand block" but finished bore "yes"
