Small Block Chevy 350

I have a Small block Chevy 350 that I am going to be putting into a 1968 Pontiac Lemans but first I am trying to figure out how to get about 550 horsepower out of it, does anyone have any ideas on what I should do? Any input will be greatly appreciated.

I had a '68 Le Mans myself. Liked it a lot.

Any chance you can be persuaded to put a Pontiac engine back in it?

between 3 and $7,000

What I am looking to spend on the motor alone is between three and seven thousand dollars. I know that the car has a powerglide 2 transmission in it right now, I am not sure about the rear end. I dont exactly want to put the Pontiac back into it because of how expensive they are to get some good power out of, I am however going to keep the original Pontiac 350 that came in the car and rebuild it just in case down the road I decide to go all original again. I am really just looking to get some good power out of it. So far I have came up with putting in a 3.75" crank and a roller cam and lifters, A buddy of mine has a real nice set of heads, I cant think of the name of them but he said it would only be pushing like 400-450 horsepower and I am really looking for around 550. Thank you all.

Are you sure you have a Powerglide??, Pontiacs came with a 2-speed trans called a Super Turbine 300 and it is different from a Chevy Powerglide. Pontiac case bolt pattern Powerglides are very rare, not normally found behind a 350 Pontiac in 1968.

transmission

I cant say for sure whether this is a powerglide 2 or not I just talked to my dad again about it and he said that it is a powerglide 2 from what everyone has told him about it. He has had people wanting to buy the car for the transmission alone.

Would you be interested in a 78 model Pontiac 400 out of a Trans Am w/45 K original miles?

If you have that much dough I would not waste my time on a small block when I could go big block and meet the power goal with much better streetability. 550 horses out of a small block on a street machine is a rather tall order, as the combo will have to focus on high RPM power and large cubic inches to meet the goal which will take away most of the streetability. Not saying it can`t be done, it`s just far easier with a big block.

a big block would be easier but if you want to do a 350 bore and stroke it to a 383 with all forged parts arp bolt it all decide on if you want heads like dart heads or if you can find them cheap enough get some vortec heads and have them redone with biger valves screw in studs and port and polish them after that choose a big cam for it and if you would like put a 100 to 150 shot on it that will give you around what you are looking for plus so after the button just make sure the trans and rear end can handle it or it will just be a waste good luck with whatever you do

not sure

I am not really looking for a new motor, I have the original Pontiac 350 that came with the car that I could build onto but it sounds like it would be best for me to get a big block for the ease of the operation so I guess I need to do some thinking and a little research into that realm of possibilities. I will however keep that Pontiac 400 in mind with the decision process of what I am going to do about a motor.

FWIW, most of the hardest-running stock-block Poncho's are now based on the smaller crank journal 400 block, w/stroker cranks. ALL the parts are readily available, should you go this route some day.
