    TH2004R kind skips through second when shifting manually

    Hi, Thought I'd see if anyone has had this unusual issue before. Few notes about the transmission: less than 2,000 miles but probably 8-10 years old. Rarely driven. 3,000 stall NLU converter, Billet servo, TV booster valve, Valve body kit. TV cable adjustment checked and is good. Fluid level...

    Timing map for XFI

    Hi, I have an XFI and was wondering what kind of max timing (under load) everyone is running. I seem to have very high exhaust temps as soon as I get on the throttle. Shoots to 1500+. Its not lean 12:1 +/-. Running about 20psi with methanol. (non-intercooled) Gonna get back on the dyno next week...

    Hot Air 3" Downpipe

    Thanks Brian. Is the ATR a 3"? If so, how much? I have an RJC flange that maybe I will modify the ATR to eliminate the elbow...? Thanks Greg

    Hot Air 3" Downpipe

    Thanks for the info. Yes, my concern was how tight it would be by the heater box..and where it comes up between the up-pipe and heater box. I have an RJC flange already and was thinking of building a 2.75" version...that would give me the added (minimal) clearance and delete the elbow too...

    Hot Air 3" Downpipe

    Has anyone used the gbodyparts Hot Air 3" Downpipe? If so, any comments regarding fit? My concerns are how close it comes to the heater/AC box and also the ability to change spark plugs. Any close up pictures (or pictures in general)? I have a 2.5" but I am thinking about upgrading to the 3" but...

    Hydraulic roller valve springs

    I have a +.050" lock already. Anyone know the factory installed height of a stock GN iron head? 1.75"?, 1.80"? I was perplexed at the minimal height I have to work with.

    Hydraulic roller valve springs

    Thanks for the recommendations. I would like to be able to re-use my titanium retainers (obviously) but if I have to change, I will. I had 26995's in the motor and since I had the heads off anyways, I wanted to up the springs a bit. I was never comfortable with the low spring rate of the 26995.

    Hydraulic roller valve springs

    Heads are off now - (had an exhaust valve seize in the guide and got introduced to Mr Piston) The K-Motion 750 has a bit too much I think (482lb rate) for the hydraulic rollers. Street application with an austemper core. The 750 would be about 378lbs at lift... too much? :confused:

    Hydraulic roller valve springs

    Hi all, Running a 69-200-8 Comp HR and only have 1.68" available installed height. (using a spring locator .060" and +.050" keepers) With a 26915 Comp spring I will have about 142lbs +/- on the seat which is fine. My concern is at lift I will only have about 297lbs +/-. Is that enough? I...
