I Was allways told the series two non supercharged car was just as fast as a series one supercharged car. This Is why I want a series two motor.

incorrect...

Series One SC
the 92-93 is rated at 205
the 94-95 is rated at 225

Series Two NA
95+ is rated at 205

Series II SC
96+ is rated at 240

what is improtant here.....a 92-93 Series I SC will KILL a Series II NA, even they are rated at the same HP.....its the untold number the toruqe....that the Series I delelops it lower than the Series II

Wow then what sould I do? To rebuild My motor.

well.......

www.seriesoneperformance.com ....anything on there you can use

remember everything available for the Series II is avaiable for the Series I excpet the I/C

you can port the SC outlet, LIM and the Exhaust Mainis, for some free gains....the only thing will need is some down time with the car....

I just want to make the observation here that the people who replied have already answered your question. You had that "I want to make my Series 1 into a Series 2, how do I do that?" question, to which the answers are: No, you can't, and you should keep your Series 1 SC because it will blow the doors off a Series 2 NA. No, you can't swap the heads from a Series 2 onto your Series 1. Just keep your Series 1. You can do a pulley and an intake, high flow cat, headers and muffler, port your manifolds and eat ricers for lunch. If you want a Series 2 SC, the best way to do it is to go buy a Bonneville with a Series 2 SC.

I don't want to sound rude, but the answers are already there.

Why are we talking about rebuilding at all? What'* wrong with yours? What'* the compression?

L67'* don't need rebuilding until about 250k miles.

regardless of what anyone says you can put the SII heads and top end on a SI short block...it is involved however...and will probably be another year before i get it sorted out and running...but in the end you end up with a SI/SII hybrid that is mechanically superior to either engine alone...especially when ya start to talk stroker crankshafts...tall deck blocks (SI) have advantages that the later SII short deck/short rod short blocks...

the ancillary advantage is that the SII heads have larger valves more refined ports and combustion chamber design that make it worthwile to try to use on the SI shortblock...and if everything works out you could put the SII L67/M90 top end onto the SI shortblock using intake spacers...

a gentleman in Austraila and i are currently the only ones working on this that i know of...and the going is slow...even with me having two SI and one SII engine to work with

most of my newer info is in a post on an Holden Invite only forum run by Locksmiff

For now i would just suggest building up your SI and making more power from it...or ya can drop an L67 into the back of your bonnie
