1970 Nova L78 Intake '569' - perfomance!!

[DarrenX33]

If the 359 is taller than the 163 then it definetly ain't gonna work. 163 won't clear a stock 70 hood. Go L88 hood or choke your motor with the 569.

The 359 is an all new creature, I believe, straight out of GMPP...the NHRA allows it & the non-original 401 aluminum heads on the L78 & L72 combos. Why is beyond me...maybe as a concession to all the whacky FoMoCo combos.

That #359 intake manifold is made for GMPP by either Edelbrock or World Products. I think the #163 intake will fit because it came on '69 Novas and the VERY similar #069 came on '68 Novas. What changed on '70 Novas?

[Mr. Chevy]

Definately do not use the stock low rise 70 intake if your looking for power.. I have talked to guys who said they have actually noticed a big difference in driveability by switching to the higher rise intakes.... If its originality your after and don't care about performance then use the stock, low rise...

Interesting, didn't know it was outsourced, but doesn't surprise me.

BTW, I think Darren was answering Chuck's question regarding his '70 Camaro...but you're correct aobu thte original poster's question, if it'll fit in a 68/69 Nova it'll fit in a '70.

Nevermind, Rob treed me on this one!

I'll tell' ya....I've got one those #569 "pancake" intake manifolds that's orignal to my LS-6 and the funny thing is, if you turn it upside down, all the runners resemble a #163. I bought a magazine from the early '70's last weekend with an NHRA Stock Eliminator Chevelle that uses a #569. In the article, they stated they had compared it greatly to the Hi-rise, that the runners measure out exactly same, and performance was equal in their limited camshaft applications. For what it's worth.

Intake manifolds are a fetish of mine. I've messed with them all at one point or another and actually used to enjoy changing them. Anyway, if you have aftermarket aluminum heads, the Edelbrock Performer RPM is hands down the best street manifold ever made. The Air Gap Performer RPM is even better, but possibly a tiny bit taller. My all time favorite intake is the Dart single plane Oval port which has been opened up to Rectangular ports. Very, very tall though.

Thanks a bunch for all of your input - it is interesting on the article on the L78 Chevelle. Like I said I am kind of making the 'Day 2' street car and I want to keep an 'original' type look but want as much performance as I can get. With these responses you guys have answered my questions...I think I will look into the air gap - will this affect any of my stock choke applications or radiator hose fittings?
Thanks again

Was that the article on Durham's 70 Chevelle L-78 car?
