455 IN THE HOUSE BABY

I kinda like how it sits. It's got the 70's drag car look to it

Roll the rear lip and drop the whole car. Otherwise, cool man.

What is the backspacing on the rear rims? I like the way it looks as it is.

4.5" rear back spacing with a 325/50 tire ...............


I OWE THAT RESEARCH TO CHRIS AKA 1973 454 MONTE THANKS BUDDY

Looks good, what kinda tire is on the back?

right now I have some BFG drag radials on there but when I get paid I am getting some newer Nitto Drag radials installed same size, guy was supposed to have them ready for me but didnt so he said in a week or so I could get the nitto's from him they are only gonna have 6 Dyno pulls on them.

Just an FYI the nitto DR's run narrow so they arent gonna be as big as the BFGs you have are.

even if they are the same size tire

I like the way the rear looks but i think the fronts are too small.

did you put the wider wheels on one side to see how it looks and take a picture?

nope they are all the same on both sides my drive is lopsided to the drivers side though because of the septic tank being so close to house

what i asked if you put the 2 wider wheels on the same side to see what it would look like and take a picture.

they would be the same LOL

both rims and rear tires are the same o yea I see what you want the 10 on all corners

Yup, even if they are the same size. Even though they list the measurements as the same as m/t or bfg they are definately skinnier. Ill try to find some pics to show you.

Found a few pics. Not the same size as your using but will give you an idea what Im saying

#1. left - 315/35/17 Nitto 555 (non DR) vs right - 315/35/17 Nitto 555R (DR)



#2. left - 275/40/17 BFG KD (non DR) vs right - 315/35/17 Nitto 555R (DR)

Here you go Limey:

Tests were performed at 25" H2O. 2.071 intake & 1.625 exhaust valves

.600	225.0	.600	152.0

Notice that the exhaust flow is nearly identical on the two heads & the low lift intake #s are pretty comparable. Only when a high lift cam & some decent compression is used are you gonna notice a difference between the two, IMHO. I've also been told that ported G castings flow just as well if not better than C castings, but that's just hearsay from the local machine shop head guy so take it as you will.
