Ah! I don’t know how I missed that… yeah it does sound like bottom end to me as well…

Also, one of those "higher voltage" yellow accel coils wouldn't do much would it? I have one in the box laying around

I'm thinking that if I do anything major to the car performance wise I'll just rebuild the 351HO that I have sitting in my garage and conver to 4bbl...

There's the sound clip I linked earlier. Dunno if it's invisible or something. I'm thinking bottom end because it doesn't sound as "hollow" as most...

Bottom end tends to be a deeper sound, like dunk dunk dunk, clacking tends to be valvetrain… hard to tell without hearing it though as everyone’s...

I've seen this done once, actually. Only problem is the TPS. That's gotta work or the whole system goes dumb. There are better and proven options....

I have 4 or 5 of them, and a few boxes of tubes. Need to purge out the useless stuff and keep the better caddys for useful tubes. At least 2 of...

Would it mess with the timing if I just left the whole system hooked up except the fuel injectors since there would be a carburetor?

just a minor point, the TFI does not need a computer to work. The problem is that you get no advance, which means it just works incredibly poorly...

It could probably be a weekend-ish project if you're more experienced than me (quite likely), have all the parts ready and won't spend time painting...

Well, I put in the RVS, which made the engine run maybe a tiny bit smoother, but didn't do shit for the clacketyclack, which was expected. Coming...

Got out to the Lincoln today to get some work done. Put in new wiper blades, quick connect fitting, and fan clutch. The old fan clutch was leaking,...

Truthfully, it is not budget friendly to try to even make it remotely fast. Really, you get what you get with your CFI performance. I have a lot into...

Oh hey, a thread. Last night, I was a party to some Woodward cruising in a sort of mismatched group of cars: C6 Z06, Suzuki Alto Works,...

That is cool. I have tubes here but they are all guitar amp tubes. 6v6 power tubes and other preamp tubes. I do remember having tube TVs and...

I agree with this and every one else. Rear gear change and dual exhaust will be the best bang for your buck

I'd say dual exhaust gears/converter. Getting rid of 3.08's you likely have and getting into a 3.27 or 3.55 might wake it up, but I've never tried...

The factory dual exhaust was supposed to be good for 15 hp. Trying to make performance upgrades with CFI, you'll eventually run into the limitations...

I plan to switch to 10W-40 with the next change (just about due but I have a busy couple of weekends coming up). Probably should've done that years...

Sluggish91 has what is likely the most performance themed CFI build around here. His signature lists "CFI, K&N Filter, Edelbrock Performer 289...

See, you could have made $300! LOL!

I just gave away my tube caddy, lots of 70's era tubes for electrohome tv's.

Right on Andy! (it better not be your last post).

Love the front end. And loved the update through the years. Great work. Be proud of yourself.

:2up: :rtr: :2up: That thing looks awesome!

Check the relay for that soldered wire. If it doesn't have it, it's not the autolamp relay. That's the ONLY "6-pin" relay in the car. The rest are...

How long did yours take? I can't have much down time as this is my daily lol
