[QUOTE="aarons04cobra, post: 15571565, member: 158184"] So long story short, my cobra belonged to a close friend who passed away two years ago. His goal was to build this car to drop 4 digit power on the dyno on a PD blower. I am in the process of trying to make his dream come true. I do not intend to drive the car on the streets under full boost. I am mainly looking to get my 1k on the dyno and then run the car on lower boost for the street. The car will see some track time but no more then 5-10 1/4 mile track days a season and maybe 1 o r 2 half mile events. Low down on the car: built SRA, t56 magnum, mac [SIZE=4]LT's, MM coil overs, no cats, no egr, no a/c. keeping the power steering. I intend to run the car on e85 and swap over to a pump gas / torco tune if i take it on any longer cruises. The car is getting a cage while the motor is being built. I was originally thinking i wanted to run a 4.0L whipple but after further research, I am thinking a 3.4 crusher and a shot of nitrous will be the safer bet to get my dyno number. I am open to suggestions, however I have zero interest in going to a turbo/auto setup like I'm sure some will suggest. The heads are being ported and re-threaded. The block is getting bored .20 over. All ARP hardware. My questions pertain more to what cams and rotating assemblies I should purchase. I have a local engine builder that I have great faith in assembling the engine once all parts arrive. I am removing the motor from the car this week. I see on lethal performance these rotating assembly kits. But I am unsure what will be best. I have heard mixed thoughts on the eagle kits for high hp applications.

What type of pistons would be best for my application? "dished, flat top, etc" What cams would be best? I have heard I would be fine with the stock crank, but im not sure I want to take the risk. I was going replace it anyway just to be safe. Thoughts? Whats rods would be best? open to any other suggestions. [/QUOTE]
