I think you have a plan.that will give you a baseline to compare your changes to that way you will be able to see your. Improvements as you make changes. Keep us updated I am interested in your progress. Maybe we can share notes as you move forward. Thx clyde

Here is a link where scotty does very minimal work on a std valve head and gets high 180s on exhaust. For the home porter. Lol. http://www.429-460.com/engine-tech-f...3987.htm#43550

Thanks for link. I have done some port work on sbc heads before and they turned out decent.

I finished the rewiring today and got it running. Still sounds the same. Everything looks in good shape except carb seems like the floats out of wack. At idle you can see gas dripping on one front bowl amd one rear bowl. I have a rebuild kit but have never built a holley 4150. I have built a few qaudrajets back in my chevy days. Im guessing its basically the same.

Found out that the vacuum to dizzy is not been used. The nipple on vac adv is broke off. Will it be worth my while buying new vac adv and getting that hooked back up or should i leave it alone.

The carb build is easy just make sure you use the right gasket and make sure everything is clean.

Get the heads ported to flw around 330 intake. Aroun 190 cfm on the exhaust. With bigger valves 2.25 in 1.76 exh valves. 1.73 roller rockers and make sure you have a good oil pump and a frpp oil pump shaft while heads are off. Check piston to deck clearance and run a head gasket that when compressed thickness and piston to deck heigt are added together add up to around .045 or so. That will make for a nice quench pad area. And don't forget to have head chambers polished. Then go have some fun. Lol but be planning a short block build with good pistons. Lol have some fun. I believe that will be a bucket of fun.

What kina of magnaflows was you talking about? I am trying to get a few parts together.

depends on how quiet you want it to be inside the car.A 3 inch inlet and outlet straight through type will work fine. Magnaflow has lots of different ones if you are going to purchase new I suggest calling a magnaflow rep and consulting with them.1-800-990-0905

I have a lx coupe tubbed and gutted with a 460 and a powerglide. The car ran a 6.60 with unported C8VE heads, a victor intake, a small solid flat tappet cam, KB hyper pistons, victor 460, and a 750 alcohol carb through 3.5" 1 chamber flowmasters. It ran 6.80-6.90's on gas. This was a very basic simple combo that ran pretty good. I put a set of old TFS cobra jet style heads on and it ran a best of 6.40 @ 109 with no other changes. I have a set of DOVE heads at home with CJ size valves and some port work. They have been 6.30's in another car and we only picked up a tenth going to CJ style heads. So those heads can work pretty good.

I have a D&D k member with hooker headers. The oil pan actually touches the k member (Front and mid motor plates are used for mounts) but it is still pretty tall. If you put in a k member get either a dropped one or get some spacers it will make a difference. My headers are a pain in the @ss too.

I still have the car but it needs some work now. but with very little work I could have it running again.

i can tell this is a big block guy

rj95svt · 04-12-2010, 08:58 AM

hehe, yeah I have worked on a few but I love the small blocks too.

If any of you guys have seen a yellow and black all fiberglass tube chassis 2006 mustang @ Steele, Hunstville, Baileyton, or Montgomery that is my dads car. I have helped build that car from the ground up. It's a 545ci 460, 429cj 4 bolt main block, TFS A460 heads ported, Solid roller, A460 single plain intake and a alcohol dominator runs 5.20's @130+.
