how much is to much

[slickmustang]

I got a 94 cobra with a soon to go in it a 342 low compression short block that D&D built with a cam they cut for it all the good parts in it with crane electronic's to retart the timing and I got a meth inj.system to go in it to cool it a little with a pro-m 80 mm MAF with 42 lb inj and lot's of other stuff but what's the most boost can I get away with on a Kenny Bell blower with a 14 lb pully that was on it when I got it.Im thinking it can handle it has anyone out there run or seen somthing like this with this kind of boost run ok? slickmustang

Too close to the limit of the stock shortblock for my comfort. What heads? What lower intake?

The short block isn't stock D & D built it with the good rods and crank and pistons with a girdle to help hold it togather because I told them that a blower was going on it and the heads are the GT 40's with a port job with bigger exhaust valves.So im not to worryed about the block unless I get over 500 hp and with the cam they cut for topping out at 6,500 RPM im not planning on running that kind of RPM very much.I put a lot of money trying to get it to berth as much as possible with the off road x-pipe and long tube headers.

I wouldn't push the stock block to its limits. I would just stay around that before I pushed it to hard. :wow:
