Thread: how level must the engine be ?

Tweet

I know this sounds like a stupid question but the intake on the 348 is slanted like a bugger and i was wondering to i want the intake more straight or the engine. i would think the intake but i thought i'd ask. ( those big blocks are just stupid heavy )

The OEM manufacturers installed the motor/trans angled down 2-3 degrees to afford some legroom in the front passenger compartment, so the intake manifold is milled on an angle to provide level placement for the carburetor. When I do an engine swap, I install the intake manifold I'm going to use and install the motor so that the carb pad is level, then adjust the angle of the rear differential so that the trans output shaft and the pinion shaft in the diff are close to the same angle.

thanks tech

carb. pad level

Hey 53 what are you putting the 348 in? Dont hear of many people using them anymore. I have one im going to be dropping in my 59 Impala . And I know what you mean about them things being heavy lol, when I pulled the original 348 and the cast iron pig of a powerglide it actully bent my dads Engine hoist!! And it took 3 of us to roll the engine and tranny away from the car lol. Is the 348 your using stock? Good luck with it!

I'm sticking the 348 in a 53 chevy pickup. your right, you dont see them much anymore so i decided to use the 348 with modern tech vs a ls1 that i could have used. time will tell if i made a mistake in judgement . i rebuilt it stock because i need this thing to be reliable on long trips and the the pickup wont need that much power to scoot it along anyway


thats a funny story about the chain hoist, a 348 and a cast PG, is thier any heavier combo . i thought for sure i was going to post a pic of my engine stand buckled over when i had the 348 on it.
