So I ruled the hear riser out. I'm thinking about blocking the passage that warms the carb with a new intake gasket and blocking the ports. If this cools the float bowl, then maybe this will be something I should do. I did not have this with my 77 even with the stock intake, and they are...

Alright, I found my heat riser from my 77, and it was in the open position. The heat riser was not stuck closed. I was hoping this was the issue, but It's not.

Tom, I have a heat riser, but there is no linkage attached to it. I can rotate it clockwise, counterclockwise. It was rotated to the left (counterclockwise). Can you tell me which way opens and closes the heat riser? I have a feeling that is my problem. If I can keep it open, then my issue...

That's very interesting. Now I remember what I heard. It's exhaust, not coolant. I'll check the heat riser issue also. I was thinking of changing the gaskets to keep the float bowl cooler. Thank you Tom

I've been having an issue with E10 boiling out of my float bowl after the engine is warm It's a basic l48, with an aftermarket cam. My 77 has basically the same engine, with an Edlebrock intake. I do not have this with the 77, but I do with the 79. Ive heard the coolant passage that goes...

Well, shocks aren't that expensive, or difficult to install. If I am troubled by this in the spring time I may just get delco. Maybe the mono springs destroyed the KYB's by over working them. Who knows. As I mentioned before, the aftermarket mono spring was way too bouncy, and caused the...

Going by what you are describing, the KYB in my opinion the rebound is too soft, to much. It's not so bad that I need to replace them, but for instance, when on the Highway if I go over a dip the back comes up too much coming out of it. My 79 acts different, and it has original 7 leaf.

The KYB's seem to rebound a bit too high. If I'm on the highway and go over a "dip" it just seems to rebound too much, as if the shocks are weak. Hard to explain, but that's what I feel. The 7 leaf is brand new, and they are supposed to be stiffer than the 9 leaf. I installed the KYB's last...

Hello Tom, The KYB's seem to be adaquate, but I was hoping for a stiffer shock. I might try the Delco's , the one's you put on, or something similar to them. Maybe the Bistein's? Can you tell me anything about them? I apologize for not responding to this sooner, I live in Michigan, and my...

I forgot about this post, but I did replace the rear mono spring with a 7 leaf. Ride height is back to where is should be now. and it rides much better. The after market spring was way too bouncy. So much so, i believe it prematurely wore the shocks out. I replaced them with KYB's.

That's sweet! The description said it came with a 350 tranny, wouldn't a big block have come with a 400?

I looked it over the best I can, and didn't see anything obvious. The car rides nice, handles great, and doesn't squeak. I'm sure it would be a good idea to replace the spring (7 leaf), but that's a next spring thing. The nuts are almost at the end of the bolts on the 79. I would like to...

My 79 rides just about 1/2 to 3/4" lower on the passenger side rear. Is it a good idea to raise the spring by turning the nut on the bolt that holds the spring? They are set exactly the same on each side which is almost to the end. If I did this, the passenger side would be turned in more...

Yes, this guy is great! His business name is Pine and 17th transmission Holland, MI His name is Jerry Mullengraff. BTW I get a nice chirp in 2nd if I get on it now. The hard part is driving it "nice". Thanks again Tom..

I picked up my Vette Friday afternoon after a rebuild. He set it up so it shifts firmer than stock, but not a shift kit. This is what I wanted, since it's a street driven car. It shifts nice and firm, in 2nd, and third. I have a 2200 stall converter, and I can tell the difference. With the...

Rebuild is happening next week. He's gonna ad a mild shift kit, and put a 2200 stall torque converter. There is a difference between L48, and L82 stall speed. He has a guy that puts torque converters together. I thought they just came in a box, Mine is about 1700 rpm. I brought the car to...

My transmission guy recommends a rebuild. He told me the modulator would not act that way when warmed up, vs cool. Anyway I added a bottle of Lucus Transfix, and it acts somewhat better, but it still kicks down when it shouldn't. If an unknowing driver were going 70 it would kick down and red...

I am going to buy a new vacuum modulator tomorrow morning. I replaced the hose, but it's still acting up. I put the car on ramps, and had trouble getting a wrench on the bolt that holds the retaining bracket which holds the modulator in. My exhaust pipe is very close, I tried a fine click...

I watched a youtube on removing and replacing the vacuum modulator. One bolt to loosen, and it comes out. Anywhere between $15 - $25. Maybe a local auto parts store will have one. I'm gonna "throw parts at it" and replace it along with the vacuum line. If the line is grossly cracked, I just...

Well, I can certainly check the vacuum hose, and replace if necessary, I of course would like to avoid removing the transmi$$ion. It only does this when the tranny is thoroughly warmed up. I'll see what I can do.
