who can guess on what numbers i might run

biggyfan1 · Apr 14, 2006

it is getting closer and closer to turning the key time and i am woundering what HP i might have a the wheels. here is what i have
302 now a 347 roller,
AFR 185's,
comp cam intake lift .536 exaust lift .544 with 1.6rr's
DUR on intake @.050 is 224 on exaust 230 with 110.0 lobe separation.
performer RPM intake,
mahle forged pistons,
gear drive,
long tubes,
holley 600cfm for now untill i can get a 750,
C4 with a 2800 stall or maybe 3000.
i was told it will be 11 to 1 compression

what do you think guys? and what do you see holding me back? that carb for now huh.

The carb is probably OK... What rear axle ratio do you have?

Your combo is very much like mine and I am taking it to the dragstrip tonight for it's maiden voyage with the new engine. I should improve on last years 13.23 I ran with the low compression 302. This engine feels like a different beast!
I will let you know.

Here's my combo:

302 now a 347,
AFR 185's,
comp cam XE274H (non roller) 230/236 @ .050"
pro prod. air gap,
KB hypers,
Hooker 1 5/8" headers,
Demon 650cfm,
C4 with a stall of ~ 3000.
10 to 1 compression
3.55 gears

All in a '66 coupe.

Screw HEI! A Duraspark dizzy for an 85 5spd GT is $55 and the box is $30. The carb is OK (with a motor like that, it should scoot! )

congrats on joining the stroker club

do you still have stock gears in your stock 8"?

600vacuum sec is very small for your set up but will be fine for break-in time

2bav8 · Apr 14, 2006

I'd guess 350 HP at the rear wheels with the 750 carb.
The 600 is going to be a bottle neck, but should have great low end torque.

brianj5600 · Apr 14, 2006

I like bigger intakes on 347's, but the 600 vacuum seems to be the bottleneck. It will be strong, but there is more with a bigger carb and maybe a Victor jr.

fastback brian · Apr 14, 2006

your stall should be good. the carb is a little small, it may need to be tuned a bit. the rear gear is probbaly a 3.00 or 3.25, it will work for your low rpm high torque engine setup.
How did your car end up with the pre 66 engine mounts? Your gonna need the 66 and later mounts and brakets if you want to use a header that will flow enough for a 347.

biggyfan1 · Apr 15, 2006

the mounts are the 1966 ones. is that what you were asking? yahh i knew the carb would be a little small but good for the break in. i was hoping for like 400 to the wheels. the car will be bottle baby with a 100 shot. i will wait like 1 year to install it tho. also guys i have some long tubes that were on the 289 and they fit nice in engine bay. i am just wondering if they will work with the AFR heads. the heads seem to have an egg shaped port and the headers are square. is this normal. what long tubes are you guys running? also i would like to thank this site for helping me with this motor. corral.net is a good site but this one seems better. keep the numbers coming and the advice rolling in. l8er

Vinyl66 · Apr 15, 2006

I don't know the horsepower you will be making, but I can tell you it will be a fun and fast car. Traction is MUCH harder to come by now than with my 13.2 second 302 I had.

I did muster a 12.44 at close to 109 mph last night in my '66 coupe first time out with basically the same combo you have.

I have started another thread about it so I wont be hijacking your's.

biggyfan1 · Apr 15, 2006

hey guys i have the part# for the header i have and it is Part #: 6901-1HKR they are hooker headers. how is that for my 347?

fastback brian · Apr 15, 2006

you have good chance to make 400rwhp. I dont think your intake, cam, carb and exhaust will get you there with only 347 cubes. And if you do step up the engine and install oxide the roller block might not live to long.
Those hooker headers will work with your combo for now, they should fit the heads just fine, your only other choice for headers will be custom 1 3/4, some company does have them off the shelf but dont remeber the name.

Vinyl66 · Apr 15, 2006

Those are the Hooker Headers I am using. They work great but I just wish I had them ceramic coated. Painted headers like to rust.

who can guess on what numbers i might run
