460 in a fox

Re-check the math - 4.2" bore X 4.25" stroke is 471 cubes. Just keeps gettin' better...

Yes it does get better...you can STROKE a 460!
Nothing like runing 550 plus cubic inches on the street .

Yeah, $2500 plus $1500 rotating assy, and over $1600 in heads. Because everyone here has that kind of money. Anyways, get a set of stock D0VE-c heads and clean up the exhaust ports and install stiffer springs. Thats good enough to get you in the 400-450 range. To make more power, either port those or go for the interceptor heads. You may want to bump up the comp too. I have D0VE-C heads with some of the smallest chambers around and they still only generate 9 to 1 with the stock pistons. Or get a pre-prepped 460 block ready for a stroker and then get a 514 stroker kit for around $1400. Thats $700 for the block and $1400 for the rotating and now you have a huge stroker for $2300. The heads and stuff are up to you but you can see that a 514 stroker is the same price as 302-351 based stroker. You'll end up spending more on aluminum heads but you'll make up that money with the cheap used intake and standard 750 Holley. Yes heads are expensive but being carbed you dont need to buy injectors, MAF, throttle body and EFI intake. Think about it:
460:
aluminum heads-$2300 new
intake-$170 new
carb-$200
EFI 302:
aluminum heads-$1100-$1600
intake-$350-$600
TB-$150
injectors-$250
MAF-$150-200
Numbers are similar, but the 460 wins if you keep to iron heads. As for weight, if you can spring it, a 460 with aluminum heads and an aluminum intake weighs as much as an iron headed 302.

I forget what the weight is, but it is a good bit higher than a 302. Aluminum heads will help as will what you have already done, but the heads take some of the cheapness out of the power.

"460 with aluminum heads and an aluminum intake weighs as much as an iron headed 302"

Can you give us some numbers or the source of your data Smock? Everything I've read, the aluminum head/intake 460 would be a good 100 lbs. heavier than a cast iron headed 302.

473.5152 actually...

I saw an '88 notch at the track this summer with a 460/C6 set up and I was impressed. He must have had a fairly mild cam because it idled smooth as glass. Looked like a tight fit under the hood , but he had done really nice clean install on it. He told me the motor was one he got from the jumk yard out of an old van, and just did a basically stock rebuild on it. It ran in the 12's . I just thought it was awesome to see that big block stuffed in a fox.

I get 471.05....

You know, I took my own advice to check out bigblockfox.com. They have some forums there. The format is so time consuming and hard to read that it is not worth anything IMO. Not to insult any fans or sysops, but that site needs a mo betterer format.

Yeah tried to check it out myself. It was like a message board time warp.
