383 Stroker trouble - Too hot?

Today at 01:51:04 PM by TIREKIKR

Drove my newly installed 383 Stroker 50 miles to a dyno shop to have it tuned. No touble getting there, but the drive back home a week later was tons of fun, until I saw steam out the rearview mirror. Shut her down, way too hot (I know...the stupid gauge was still at 120), boiling gas in the carb and couldn't touch the oil filler cap for 3 hours. Towed it home. Started up the next day like nothing happened, but have been unwilling to drive it until I figure out the problem.

Heat tabs on the back of the heads are both melted. I'm worried he somehow fried my engine. Just checked cylinder compression, and everything's between 100 & 94. That's it.

He mentioned moving the timing way out to 32. From what I've read, I wonder if he set the timing too far in advance and early detonation in the cylinders cooked it.

I have good water flow. Haven't yet checked the timing. Long-block was built by Phoenix Engines.

Bore= 4.030
Stroke= 3.750
Compression Ratio= 11.1

I've got to keep this simple. I don't like the whopping cam that's in there (Int-508, Exh-532, Dur@0.5: 244-254, Lobe 112), so the top end needs to come off anyway. Would appreciate input on what else I need to do before taking it apart, and what to check after the heads are off. If the rings are shot, maybe I'll go to an LS. But gotta stop spending $$. Thanks in advance!

Front brake line replacement questions

December 03, 2021, 09:45:30 AM by ih8vols | Views: 70 | Comments: 2

I have a 79 Silverado Stepside. I've been having issues with it pulling to the left pretty hard when braking. Since it's winter, I've decided to replace all the front brake lines. I ordered replacement pre-bent steel lines from .

Couple questions:

The steel lines don't line up to the old ones exactly. In order to secure it to the frame, I'm going to need to bend them some (I have a tube bender). Is there any issues with brake lines having a 90 degree bend or is that a bad idea?
How do you bleed brakes on these trucks since it has the proportioning valve? I bought one of the aluminum overrides. Do I use the override, bleed the brakes and replace the override with the valve when done? Will that introduce air back into the lines?

Thanks!

Acceleration Problem After Pulls

I have a stock 78 C20 with a 350 and a QuadraJet and factory HEI, and I have been having some issues with drivability after going 3/4 throttle or more. Truck starts, runs, and drives fine until I get on it. The first time getting on it goes well, but after that it bogs/chugs bad on light acceleration, especially from a stop. Changed the advance weights/springs/centerplate with no luck in solving the issue. Also if I leave it parked for a day then the problem seems to go away until I get on it again. Any ideas?

Sanderson bb8 headers exhaust bends

I have a question about Sanderson bb8 header install I saw on the forum.
I just wanted to know the bends for the down pipes that come off the Sanderson collectors. What radius pipes have to be used on both driver and passenger side? I was thinking a 45 degree and 60 degree? The collector adaptors have a slight kick up to them. Trying to do this myself without going to exhaust shop. This is on a lowered 79 C10. Trying to keep exhaust as close to frame as possible. Thanks for your help.

I'm FORKED - Cant get a Clutch Fork to Fit in my '87

November 29, 2021, 09:46:48 AM by ToppDogg | Views: 110 | Comments: 3

Hello,

I CANNOT get a clutch fork to fit into my bellhousing and onto my shaft. Any thoughts or suggestions are appreciated! I have a 1987 Chevy V20 I got a few months ago. It needed a new fuel pump, fuel tank, new starter and new clutch. She (Katy) starts and runs now, but I have yet to throw her into gear... I have never replaced a clutch but I got Youtube so it seemed easy enough. Everything was hunky-dory until I went to put on the new release bearing and clutch fork, I've spent at least 4 hours trying to get the dang things on there. I have tried a variety of different auto parts stores and they keep giving me a clutch fork that is not quite the same size as the one I got off the truck. I got these numbers off of the clutch fork, 15592270, I think its the original GM part but when any auto parts stores look it up they all come back and give me the same part that doesn't fit, CF-116. I have tried telling them I got a different tranny (Tailshaft Housing Casting Numbers 15597793) but so far I haven't had any luck getting a fork that fits. I cant use the fork I pulled out because there's way too much play in it and I think that's part of the reason that the clutch I pulled off was so worn down. How can I find the correct fork?!? I attached a photo for ya'll to see how perty she is.
