1971 Chevrolet Chevelle

Hey Jeep,
I did get up the track the last test and tune Saturday Oct 26th. Ran a personal best of 10.40@127.73. There is a low 10 in it for sure with some more tuning on the launch. With some Nitrous I'm sure it would be in the 9's so I can be in the club on this post. Spring is going to be fun.

1972 Chevrolet Nova

Paul, I almost went up on that day but something came up. Looking forward to get the Nova back up there. Want to sneak into the 10's. I converted to Holley Fuel Injection and made a cam change. We made 604.7 HP on Chad Golen's dyno at 6700 RPM on pump gas. That's 70 HP more than what I made with carb. It went a best of 11.03 @ 123.14 with the old setup. I've had some health issues for the last couple of years but hope to get back to New England Dragway in the spring Driving

According to most calculators you should be in the mid tens already. Either you are mistaking an Impala for your Nova or you need to work on your suspension to get your power to the ground.

A Nova will weigh 3200 to 3400 pounds not the 4300 pounds an Impala weighs (which would have you in the eleven teens with your current wheel horsepower).

All of the calculators work off of Newton's F=ma (E.T. equals horsepower divided by weight)

Not sure what the Nova weighs. According to the fuel system on my car it is making 700HP@7200rpm. I know at 3525lbs I should be in the low 10s. Just have to get it to 60í better. All I did this session was adjust tire pressure which got me to 1.4 second 60í. I think if it sticks it should be able to do better than that. Still some possible converter shenanigans required (8" 5200 stall). Still running a relatively tight converter 9" 4000 stall).


On another note: I have been trying to reach Smoke but he hasnít responded. Hope he is doing well.

Though Big Dave was writing to me. My car weighed 3740 pounds with me in it when I went 11.03. I weighed 235 at the time. My car was still running factory Air. Ran with a full 3 inch exhaust made up with pipes from Hooker tat is pretty heavy. I was getting 1.50 60 foot times and locking up the converter in 3rd gear around 5200 RPM Driving

Hi Jeep,
That is getting off the line well with the 3.06 first gear in that 700R4. Lockup is cool too sort of best of both worlds with no slip on the top end.

I too run full exhaust it is 3 1/2" though.

Youtube link running 10.40@127.73 through the exhaust. 2 step working now with the Holley HP EFI.

Paul,
I'm pretty sure that was with the 3.06 first gear. I changed to the 2.84 first gear, but I forget when I did it. Actually, I didn't do it. I had Jef Lynch, the Hot Rod Genius, from Townsend do it. It's good for something like 700 ponies. Smartest car guy I've ever known. Would you know Bob Merchant of Steve George? They live up that way too. Driving

Hi Jeep,
2.84 sounds like a nice improvement. I always thought the 3.06 gear was way too low and that the jump to the next gear was too wide for most combinations. Jeff does have an excellent reputation for his knowledge of all phases of car work and its what he does for a living. I have had many people ask me if I know Jeff since I do live in Townsend. I have no doubt he would be my go to guy for stuff if I needed help. Bob Merchant doesn't ring a bell with me though sorry I haven't heard of him.

In short I do all my own stuff really besides engine machine work.

My background is I attended a few semesters of EE courses at UMass Lowell in the early 80s. I decided EE wasn't for me back then and made a move to the Automotive field. I attended the 18 month program at ITT Tech Automotive in Chelsea, Mass. Graduated at the top of my class in 1988. Knowledge is certainly relative to your educational background, experience, aptitude and passion. After graduating I worked at Saab as a tech for a few years and did take some factory training while there. The shop didn't recognize ASE certifications at all. The environment was really too clicky internally for any type of advancement. Shop foreman had his pet tech and stuff like that. As a result I got out of the business back in the early 90s and went into the telecom field. Since then I have been doing my own thing automotive wise picking and choosing what I take on the side and playing with my own toys.

I'm still enrolled in the UMass EE technology program at night and take coursed when I can. Latest job just has me travelling a lot so it is difficult to pursue. LOL.

I've been a motorhead for as long as I can remember. Put together my first engine when I was 14. Basically the short block. The heads were already done It ran very well all things considered. When I was 18 or 19 I was making what a lot of adults were making but it wasn't much so I went into broadcasting as a radio announcer for 34 years. All the time I also worked on cars. I worked in a machine shop basically so I could do my own stuff. i made whatever minimum wage was back then but I learned to do work correctly. After Broadcasting ended one of my buddies got me into the GM Training School. That's where I first knew of Jef Lynch. He had been an instructor at the school at one time. He showed up a couple of times and the teacher's were really impressed with him. Years later at New England Dragway we were at a Wednesday Test & Tune working on a Nostalgia Dragster when he came over to chat.
I didn't recognize him. He mentioned something about the school and I mentioned about this guy who would stop in and people would just about genuflect in his presence and that his name was Jeff. He said "Jeff Lynch?" I said "No, I think it Smith, or something like that!"
To this day I call him Smitty. I spell Jef with one "F" because he wrote the Fuel Injection manual for General Motors. When he did the publisher suggested he only use one "F" in his first name to be different.

I was always proud of the fact that I did almost all my own work. Now I've slowed down a lot over the last 4-5 years It took me about a year to get the engine back in my Nova. I also installed Vintage Air which killed me working under the dash. Jeff did my transmission a few years back.

Hi Jeep,
Yeah some of my earliest memories back at New England Dragway in the late 60ís as a toddler on my dadís shoulders got me hooked. Laughing I do recall you mentioning working in radio broadcasting for many years when we were at the track with your son. Life does take you down many roads. Learning the craft never ends. There is definitely something about building a car that makes the car take on the personality you give it.

Health is certainly important too. My buddy Gary who did machine the intake and fuel rails on the car now passed away at 52. Sadly I never got to take him for a ride in the car because he passed before the car was running.

The GM school must have been interesting. Especially when fuel systems were going through significant changes from carbs to injection. The Saab mechanical fuel injection training class was cool. Very simple design that worked well for years before the electronic version replaced it. Small world indeed running into Jeff later at the track. Cool story!

I hear you regarding working under the dash. I remember the heater core replacement on the Chevelle. It turned into firewall repair since it was hacked before I owned the car. Which was followed by having to replace the jute firewall insulation and a heaterbox rebuild. No fun at all. Glad it wasnít an A/C equipped car!

Hope to see you at the track in the spring. Who knows I might put some more pipe in the car and get my competition license. Under 10.0 isnít too far out of reach.

Going to run the March meet hopefully. Been down almost a year.
