326 is a great motor. (No worries, all American engines leak from everywhere.) One of the car shows on TV just rebuilt a 326 and got almost 400 hp with not to much money.

One of the car shows on TV just rebuilt a 326 and got almost 400 hp with not to much money.Hi folks, I just purchased a 1967 Lemans with a 326 & a 2 barrel carb. The car is pretty original so I want to stay with the 326 for now but I’ve never owned a Pontiac before. My experience is with Chevy small blocks & my previous Buick 350.
Right now the 326 runs decent but everything is leaking so I’m thinking of pulling the motor to reseal it, maybe freshen it up depending on what the compression readings are. What are my options at this point, can I make the little 326 a decent street runner or should I just start saving my money & energy for 400? Is it worth doing the traditional cam, four barrel intake & headers or just move forward with a new build?
None of my cars and trucks past and present have leaked, 25 years in this house and not a spot on the garage floor and all of them American ....just saying326 is a great motor.

Hogwash. I resealed my '67 GTO 12 years ago and it doesn't leak a drop of anything. I can drive it 260 miles to visit friends in NorCal and park on their cement drive overnight and not one drop. Don't try that with any late model German car!326 is a great motor. (No worries, all American engines leak from everywhere.)

Yeah... but you dont have any breathers! So a PCV valve is useless.It does have a PCV valve, I pulled it & it rattled so it’s not stuck. Here’s a pic under hood, I’m not sure that it’s the proper hose routing but it looks old…
No, it's not useless. His system is a 'closed' Type 4 system. We've had them in CA going on 60 years. No open vents allowed. This state was screwed up even back then. The closed system works just fine, sucking crankcase fumes into the carb and burning them. The open breathers are preferable to stave off oil leaks when you have a worn engine with a lot of piston blow-by.Yeah... but you dont have any breathers! So a PCV valve is useless.
Buy two, they're smallThanks for all the advice, I’ll have a breather on it by the weekend!
Ha! Will do!Buy two, they're small
Not mine 🤣Buy two, they're small
PCV is routed correctly, but the T fitting is not correct. It should be a nylon F fitting. Ames is reproducing them.It does have a PCV valve, I pulled it & it rattled so it’s not stuck. Here’s a pic under hood, I’m not sure that it’s the proper hose routing but it looks old….
