GM would not attract people to there "sporty" car lines if the HP went backwards and dropped (unless there was a GOOD reason for it). The S3 engine is the same or MORE HP then the S2. And as mentioned, less potential inner engine problems.

Franks build should make that Monte like a brand new street machine!

 

Well I'd be willing to bet any money that my 3.4 Monte would make your Monte look like it's standing still in its current state!..........hopefully

 

No the series 3 is rated at 200hp I'm sure
I was going to go for another L36 which was from that impala i mentioned a few weeks back but I decided to go with this L26 instead

 

Thanks for that Info Jerry

Let's hope Jason

I bet it would mike :P haha

 

Oh :P I didn't see it was the series III :P Yeah sam motor my brothers 04 GP GT has.. My car is faster but only because his car has the extra weight.. So your car will be getting faster if anything then

 

Thanks man, I'm sure my monte will feel much faster than it used to be since I'm freshening up this motor and all

 

So i got the WP pulley from an older bonneville today for $5 along with a coolant reservoir hose i tore my original one when i pulled the motor haha

anyway i went to autozone and i had to order the cast impeller WP, it was only $21 and the paper gasket was like $5 or so. Should be there tomorrow noon. i also returned the cheap valve spring compressor and the plastic WP gasket i had originally bought too. so when i go to check out, the lady starts laughing lol she's like "oh WOW i owe you a penny " so it felt like i got the WP and gasket for free after returning the 2 things haha

 

Man frank you are getting close now !!!

 

the series 2 (L36) and series 3 (l26) engines make the same hp as stated, but the 200hp is at the crank so actually your only getting about 160whp

great progress frank looks great so far!
