Hey guys...
Looking for another cam selection opinion..... I have a stock (at the moment) long block on my '87 GN. I have just purchased a TE45A turbo. I have a spare set of 8445 heads and stock intake with doghouse. I was considering hand porting my spare heads and intake and getting ready to swap them out one weekend after I get the TE45A and my 60# motrons. Current mods are in my sig. A 340 pump has been ordered... so it will go on as well. I was thinking I might pull the engine to do the head swap.... cause I was planning on doing the timing chain/oil pump at the same time. This would be a good time to upgrade the stock cam. I was considering something only marginally bigger.... say... make good power til 5500 RPM instead of 4800 RPM. From what I have read... a 206/206 comp cams flat tappet cam might be enough. I kinda want to not have to upgrade my springs (Comp 980's).
So.... how big of a stick do I need to pull to 5500 RPM's on a full weight solid roof street car..(with the hand ported 8445 heads)..?? Will there be any loss of low end? Will it still idle smooth?
I guess... I have one more question.... Is it possible to pull the cam with the engine in the car.... w/o removing the a/c stuff in front of the radiator? If so... I might just do all this stuff in car.....
Thanks in advance.
