Corvette project car

1965 Impala 327 w/Powerglide engine

AKA the 275 hp L30

Oh I forgot it's a swapped engine.

What kind of cam do you have that allows you to make peak power at only 3000 rpm? Is it like .250" of lift or something?

I don't know- never looked up the stock specs. The HO engines of that year were .444", but this isn't an HO motor.

Same number cast in block as the original engine, incorrect stamping on the front pad.

So what good is an additional ~10 rwhp (= 16 hp @ crank) when the peak hp RPM moves up 200 rpm for a tiny motor in a lead sled like a 4,000 lb+ '65 Impala?

You need variable valve lift.

Comp Cams recommended a 218/218 .454/.454 with 110 lobe separation cam. I was actually starting to lean towards that one anyway.

[280Z Turbo]

It's come to my attention that flat tappets are supposed to be flat. I guess this is a common issue. I actually thought it was supposed to be dished because they all looked like this.



Got the bushings out thanks to a 1-1/8" hole saw and a lots of chiseling. This particular arm is questionable. The spring seat is tweaked and it appears to have been welded as well as reinforced for some reason.

Nice Skechers.

Anyways, man this is really turning into a serious project

Nope, I'm just making it driveable. NCRS stay away!

Anybody know if hypereutectic pistons are necessary for a mild build? I can get hypereutectics for $255 or cast pistons for $98.

[Secret Chimp]

No, you're not going to be pushing the strength of regular pistons.

[Soup DeVille]

Anybody know if hypereutectic pistons are necessary for a mild build? I can get hypereutectics for $255 or cast pistons for $92.

You probably don't need them: but for an extra hunnerd dollas; it may be worth it.

They also have a special coating on the skirt. I guess that's a good thing.

Also, this normally goes for over $600:

Hypereutectic is a stupid word that tells you nothing about the actual composition and construction. So rephrase the question with specific examples, or just go with the standard cast piston.

[280Z Turbo]

Extra-crispy recipe pistons with silicon seasoning.

Just pistons or with rods?  You might want to get some better heads in the future, or put on a blower.

Well, as far as that goes, so is "cast."

Uh, no. "Blowers" are for Cletus and Bubba.

[Eye of the Tiger]

True enough. I don't like any of these words. Get a metal piston.

Well, I was going to use ceramic, but OK.

I had stock low silicon pistons in my Nissan L28ET with 9-10 psi of boost, so I think a big lazy V8 can survive with them.

You'd probably be fine with rough cast pig iron.

[280Z Turbo]

Cast iron? Do you think this is a Model T?

If it was just a little less money a little less Texan...I'd go for it.

The frame is really the biggest thing holding the car back. I'm actually afraid to autocross the Corvette until I get a new frame because I'm afraid the frame will flex too much and crack the body.

Once the frame is replaced, the rest of the problems are cosmetic. I can live with that.

If you're serious about making the car something you can enjoy for the long term, you need to take the plunge.  Seems you're in a good position now to do that now...before you get too entangled with other responsibilities of life that creep up on you.

[GoCougs]

Q: So exactly does a frame get dents?
A: Abuse. Should avoid.

[280Z Turbo]

I've got a lead on a '66 frame in the southwest.

[hotrodalex]

I saw this car over the weekend, looked pretty good. You could do the same headlights.

Alas, I no longer have access to projectors from a scrap bin. I think just not driving it at night is a better fix.

My plan is to leave the fucked up fiberglass alone because fixing it is too expensive.
