Inliners International Forums General Discussion Vortec 4200 Vortec 4.2

Does anyone know the internal specs of a Vortec 4.2 Inline 6? I have searched the whole forum for 'Vortec 4.2', 'Vortec 4200' and 'Atlas LL8'. Lots of good info, just not what I'm looking for. I have found on other sites the Bore is a claimed 93mm and the stroke is a claimed 102mm with a claimed 103mm bore spacing. Or 3.661", 4.015" and 4.055" respectively. Is this correct?

If you go to your local Library, a Motors Manual will have all that infromation. Lay it on the copy machine & It's yours forever.

Your local Chevrolet Dealer will have it too & the Parts Dept. will get you a "spec sheet".

Good luck.
