Not bad…….Quote:

Well, wayyyy better than “not bad”. Before checking the video I broke out my Sennheiser Momentum wired headphones, made sure the audio would run through my best DAC, and hit “play”. Definitely music to my ears.
The sound of a solid lifter valve train is an acquired taste. Old fart story, bear with me - back in 1960 my buddy buys a brand new 1960 Corvette, Honduras Maroon with a silver cove, and the 579D code 283ci, 290 HP fuel injected engine. Solid lifter valve train. I loved the sound. But my dad comes out to look at it, and he is the classic shade tree mechanic who never met a car (or truck) he couldn’t disassemble and (almost) rebuild in the driveway. He looks at the idling Corvette, shakes his head, and asks “is it supposed to sound that way?”. I'll never forget that.
Wish Second Street had gone that aggressive. You done me proud.
thank you Fred. It definitely is spicy. 253/261 duration on a 109lsa,, tuning idle is going to be fun.Quote:

oh yeah, gotta get a heater core too. I WANT to delete the ac box, but i do not want to remove/possibly crack the upper dash pad. it really sucks getting to those back 4 valves on the passeger side with the ac box
Second Street refused to even consider an electric water pump. Felt it wouldn't pump enough water at 7,000 RPM to handle the 300-shot cooling load. Some people claim the stock pump cavitates below 6,000 RPM, and that concern is documented in the SAE tech paper on the the development of the LT1 reverse flow cooling system. Which leads me to believe Second Street knew how to correct that. I had supplied a new OEM water pump for them to use.
They were also dead set against filling the block. Claimed they had cooling problems with every LT1 that came in with a partially filled block.
Sometime I'll have to play the video of Baxter's final build - 1,350 HP on a 383ci Dart Iron Eagle block, Brodix heads with the spread port exhaust, huge Vortech S/C. Audio is amazing. First pass off the trailer (at Maple Grove, qualifying pass for NHRA competition license) 8.766 @ 160.37. Well actually the 2nd pass.... first pass he was running wheelie bars and when the front end came up the wheelie bar hit the + post on the 16 volt battery hanging under the rear bumper, and blew the fuses. Never ran the bars again.
Fred, you should write a book of your hot rodding experiences!Quote:

I am still debating a pcm upgrade to a holley. I saw ellwein installed one in a hotrod and explained what i had to do using a holley and the torqhead sensor kit. also a second nozzle or just going plate
