Gets hot and stalls out
Good evening all, here's my update. Unfortunately, the parts that I was waiting for didn't fit, so I had to reorder. Very, very frustrating, but gave me an opportunity to step back and do some reevaluation.
I'm in the middle of swapping from braided SS lines to solid lines at the recommendation from the forum, but I read on Holley's site that they recommend either SS or braided. Well, I've already taken down the braided, so I'm continuing on that path but with some adjustments: I'll be covering the 3/8" line in Heatshield product, and then covering it again in 3/4" Jegs heat shield product that will cover not just the SS line, but also all of the rubber line from the fuel filter and the carb connections. Connections to the fuel pump will be handled by 6 AN fittings that are being changed from a 90* right out of the pump to a straight connection, which will actually route it away from the block for about 50% of the run to the carb, meaning that fuel should be cool...really, really cool...by the time it hits the carb. Long story short: along with the .25" carb spacer, there's just no way that fuel will boil before or into the carb.
I also looked at the coil. Despite my assurances to the group that I'm not going scattershot, on inspection I got concerned: the coil had a shallow dent on the cylinder body plus the bottom corner (between the bottom and the cylinder body) was compressed, as though it was dropped. Upon some research I also found that the MSD coil should be oriented vertically, not horizontally as I have it. And, just to throw a little bonus out there, I think I bought that coil in 1995. So, another long story short, between age, damage, heat, and vibration, I thought it prudent to just go ahead and replace it - so I did.
I'm traveling for work this week but will give another update when I can. In the meantime, and just so I can hear the collective forehead slap from the forum (lol), I'm considering pushing the HP from it's roughly 412 dyno'd amount (I'm sitting in a hotel and don't have the exact numbers in front of me) to a 500+ hp build. Let the criticism begin, but I don't think I need to make a lot of changes to get to that number. And yes, I understand that will not help the heat issue at all.
