Re: New Owner - 1990 #1165
Welcome to THE BROTHERHOOD OF THE BEAST!
1201 here. Just for a point of reference, mine too is ported including plenum, IH, & heads. And, SW headers w/ 3" exhaust & SW "X" pipe. With stock cams and TB it is at 432 rwhp (before last tweak to the porting - /85% = 508+ HP @ the crank. Pete Palatsidis phased the cams and Mark Haibeck "dyno'ed" it (last). My point is, letting that LT5 BREATHE (porting) really wakes up the BEAST within with NO ILL effects to street manners - a real sleeper at idle that screams (and pulls!) to 7000+! You're find the difference VERY welcome (over the former 'TPI' motor)!
