Slice

This is my first build, and I've tried to go slow and research everything but not totally confident in my choices, so anyone who has an opinion, I'd love to hear it.

First, I'm looking for a best of both worlds situation, meaning that I want the car to cruise around with the family and not worry about overheating, but I also want to blow the doors off my buddies GTX.

Right now the block is bare and bored .060 over. I bought eagle crank and rods, ross alum flat pistons 10.5 :1 comp
Lunati hyd roller .530 intake .550 ex dur @ .50 231/239
Eddie RPM perf valve job and minor port cleaning basicly ootb
6 pack 65 jets in center and 71 outboard
Comp magnum steel roller rockers
hooker competition headers 1 7/8 to 3" (might have to go TTI for plug clearance)
4 speed
Dana 3:55
70 Coronet R/T

I think that sums it up-

I'm mostly concerned with the carb jets, cam specs and header primary tubes, but any other advice is welcome.

Slice, small block? with a 4speed and 3.55 gears that cam should be good. stock length crank or stroker?

Slice

It's a big block (1969 440) 500" stroker.

Hate to tell you, but you cant really ever have both.

You either get a fast car that'll hook and run semi hot, or you have a stocker thats great for daily driving.


Some drag radials and I think you'll be set, otherwise you're going to be buying new tires every month

If I was to redo it ,more duration and bigger heads

67 GTX

how does the car run with 93 octane and 11 to 1 compression?

maddawg57

Set the timing back a little on the street,havn't heard any spark knock and plugs don't show any.Motors been in the car since 2007.

67 GTX

has there been any big noticeable difference in power with the retarded timing?

I am running 34 total and a Proform Street Series 850 carb at this time and yes it's a little slower,but still plenty fast for the street.
