intake manifold
Hi guys looking at changing my intake manifold on my 69 350 Vette. Engine is a real 350/350 horspower and has a edelbrock torker 2 at the monement, came on the car. Got dyno'd at 388 horses at the flywheel the other day.Here's the problem idles fine, bad running on normal street driving, goes like an appocolypse at full throttle. Decided to do away with the torker2 cos i believe it to be more suited for a strip rather than street and go a dual plane but dont know what i should go for! back to origional or aftermarket? is the origional manifold same on all 350s or was it different on the 350/350 horse? and will it perform? still want some performance but drivability too! help?
running a holley atm but also thinking of going to a rochester! any ideas guys?

it all depends if you are looking for originality or what i call "day 2 mods". ive always ran edelbrock intakes, they always perform well and are priced right for me. my friend has a weiand street warrior on his vette and loves it. its just what you want to run really.

Don't think he will get it under a 1969 hood. The 69 LT1 had to have a hood bulge to get the LT1 intake to fit. This one is a little shorter than the LT1 and will take either carb.

just an observation, i knew a lot of guys that said the LT-1 intake contributed more to that engines performance difference over the 350/350 than the cam. and said the 350/350 with that intake was a better street engine.
i have the R.P.M air gap on mine and it is a great intake,could not recommend anything more highly.
i don't know about your hood clearance but some say it wouldn't fit on my 79 either but it did and i have a 1/2 in spacer too.

Weiand is good and they are overseas like most all else now. Youll lose some of that top end blast but make up for it across the board with useable torque been there done that wiht the Torker 2 and a 300-36 Holley. Give/take
If the cars done at 5500 DP is the better choice period.

I'd think you'd make about the same power with the performer air gap. Which is the way I'd go if you don't plan on spinning past 5500 rpm and you doubt go original. Before you pull the carb, use modeling clay on top of the breather to establish existing clearance, then before you pull the intake measure the pad height, edelbrock has a diagram on doing this as well as the pad heights for all there intakes. Good luck.

broblem is she runs rich on a few cylinders, and lean on others till u put ur foot into it, fawl's half the plugs up and starts running crap. cleaning the plugs after every long drive cos drive ability deteriorates. great power though. running 4:11s at this time
