I was just wondering if anyone used a 350 XTreme block or nose anyone that used this block? Is it a good block to build on or junk? Thanks Dustin

CHEVROLET 10067353 GM Goodwrench 350ci Engine OEM PERFORMANCE DEALER DIRECT
YOUR WIFE CALLED N SAID IT'S OK! 12681429 $50 VISA CRD


x2 blocks a knockoff. Ebay is flooded with no name look a like stuff be careful out there. Its cheap for a reason

Got fooled with some knockoff "manley" pushrods yrs ago..looked the part outside hardness was spot on. The metal inside crumbled like a dirt clod couldnt believe it..nothing like the real thing;could never figure out why the car never made ANY power and all kind of valvetrain noise. 60mi later tore it down destroyed my entire valvetrain they were flexing like noodles. Valve tips seats etc ruined.

If you do buy it take it right to a machinist ck th harness and $$$ for alot of machine work. I wouldnt do it..

The metric "10.9" main cap fasteners was my first clue.....

Second clue is price.... an equivalent Dart Little M is $2900.

"4.125" bore is NOT a 350, unless it is destroked
shouldn't even be calling this a 350 block with that bore
