Being a two wheel drive you can take more HP

You dont use the crank sensor unless you are using 96+ efi, the timing cover is debatable as the standard style will fit just be missing the 2 bolt holes. Either way those composite timing covers are throw away and are supposed to be replaced when removed or they will leak.

The crank sensor is to plug the hole so oil don,t come out

I don't know anything about aftermarket vortec heads, but I know GM vortec heads have different casting marks on the ends. But if that is truly a vortec engine, yeah, go with that one.

I should learn these markings.... working in scrap and all.

I looked at one of these GM crate motors and what killed my interest was the combos they used (cam, heads, etc) wasn't that great and if you changed ANYTHING on it to suit what you wanted, the warranty was void.

Guy around here rebuilds a motor with a 3yr warranty for $1700. Has a good rep. There's another place in NC that sells on feebay but you can deal with better prices directly. They're about the same with a 5yr warranty and loads of great FB (online).

To many damn options, I looked and looked for local rebuilders and they claim they are hard to find because of the 350 block, claims they only are building hemi and ford motors. I found some engine rebuilders and I gotta drive 8 hrs to Arkansas. They want the core, mine is toast because I threw that rod. They gave me prices of $1300 with core. I guess I need to go to gm , summit , all the reviews weren’t that great on some of the crate engines. HELP !!!!!!!

I see that engine runs on premium gas, every vehicle in my yard runs on premium lol

I would do this considering free shipping and probably no sales tax.

I dont even know if I would put a cam in it, save the warranty as 250hp is decent enough.

 

[christopher jones]

That looks pretty good for the price, I went to a shop and they quoted me $3400 for a 350 with 400 hp and $3800 for a 383 stroker with 460 hp

30 month 50k mile warranty, though

this gets my vote, its 123 more HP/70 tq and still has a warranty.

Do you have that engine in your truck

sorry just saw this, no I didnt purchase that engine and dont have the truck anymore. Guys on the corvette forums are giving the blue print engines good reviews and they come with a dyno sheet proving what they are making what they say.
