I am debating on keeping my 6 or upgrading to a 289. Who has modified a 6 and have you gotten any good horsepower gains? Are you able to achieve a good sound out of it? I am not looking for a race car here with huge horsepower. Just enough to get up and go a little.

 

2bbl carb, header, different distributor, maybe a cam, different head.

I had the first 3 and did a late model 5 speed swap, and it had some good pickup.

I then did a 302 swap and it cost me $1000+ and that was with me already having a 5 lug conversion, V8 driveshaft, and 8" rear end.

 

you mite consider swapping for a V8 car ..

 

food for thought.

I put my car on a dyno with a 289/bored 40 over with a very mild cam, intake, and carb kit.. it made 157 RWHP and 217 RWTQ.

If power is in your vocabulary, than the number 6 should not be.

 

My 6 was predicted to have 100+ to the wheels. Stock they make 80. I wanted to turbo mine, but never got around to it. There is a 200 6 with a couple thousand in it that made 211 to the wheels.

 

Thanks for the input. I don't wanna swap the car for a v8 can because its a car we have had for a long time. If anything I will just upgrade the car to a V8. I am just not sure if I want to do that yet or not.

 

What did u have done to your 6?

 

It was bored .040 over, 2bbl Holley 5200 carb, DSII distributor swap, Dual outlet header. Then I had a T5 put behind it instead of my old 3 speed.

 

Thanks for the info. Sounds like a way I might go. Do u remember what the motor work cost u. Boring it .040 over?

 

Also has anyone had any experience with weber carbs?

 

I had these side drafts on my Lotus.

You'll need a Uni-Syn to synchronize each cylinder.

 

I have the same Webers on my 67 Lotus Elan +2. You could hear them sucking air at WOT. pretty hard to sync but they are a work of art. (I need to get off my a** and get that car running again)

 

All analog baby! We don't need no stinking ECU. lol

 

The previous owner had the work done when the engine blew. It cost them over $2000 to get it done. Getting it bored isn't necessary, my grandfather had a 66 with the same things done to it except the bore and it was pretty much the same performance wise.

 

Ok thanks. I think I may stick with the six for now until I get some extra cash and in a couple years upgrade to the 8.
