Oh that's great news man! How large are you going? What is the current TB size (40mm?) Really looking forward to your dyno numbers..!
In other news on my project na, I've been making some calls and doing some research. The next two weeks is when I'm planning to make the mods, but as I'm learning more about this I'm starting to get scared. Here's why...
I found a shop (about 45 minutes from home) that has connections with a race shop that does head work. He says they will do the .020 decking, runner matched porting, a new valve job, and re-assemble the head for about $500.
However when I talked to Jerry (in the tech. dept. not customer service!) from Crane Cams, he indicated that I might want to be careful about who does the porting work. If it's not done correctly it could actually HURT my HP rather than help it, apparently the flow for each chamber has to be balanced or else the motor won't run properly at high RPM's (which cuts HP). He's heard some horror stories.
Also, he said since I'm not planning to race it very often he thinks doing the porting might not be that helpful. Porting is really best above 4,000 RPM as the engine breathes better, but real HP and torque comes from the cam lift. He suggests I should save money on the porting, add the cams, do the decking and just add some underdrive pulleys to give me a similar high RPM benefit without the risk of someone f***king up my cylinder head flow.
If something does go wrong in the porting job it will cost me a TON of money to get the head pulled again and fixed/replaced. Which is a cost I doubt I can get the race shop to cover even if they do something wrong.
Did your shop in FL give you pre and post flow bench numbers on your head work? I've been told that is the only way to prove the work was done right. This came from Tom down at Champion Racing Heads in FL, who I spoke to yesterday, and he was reccomended by Crane as one of the best in the business when it comes to head work.
I'm looking for about 30 HP, in the end. So what are you're thoughts about this? Did you have any of the same concerns? Did your SRT buddies show/tell you anything that eased your mind?
I'd appreciate your input.
Tom
