I have a blown 426 hemi in my GTX. I removed the blower and put dual quad intake and Snipers on it. It runs good except for some popping out of the exhaust at idle, which may be from the lower compression I’m assuming. The whole build has about 150 miles on it since being built in the late 80’s...
I just pulled the 6-71 blower off my Hemi and want to keep everything under the stock hood. I would like to be around 600hp. Is that possible with an original 68 block or do I need an aftermarket block? My engine has about 100 miles on it since being built in the late 80’s. It is .030 over with...
I have an original 68 426 hemi in my 68 GTX. Not a “J” code car (originally 440) It has a 6-71 Weiand blower with Holley Sniper EFI. Runs great. Tuned to about 700 horsepower. I was trying to sell it to put a 572 back in and keep it under the hood. If I sold the blower and Crager intake, would I...

I am trying to adjust my rockers on a 426 Hemi. It has hydraulic lifters. It was running fine until I decided to adjust them while I had the valve covers off. I have the picture of which valves to adjust after each 90 degree turn. Tried that and now runs like crap and won’t idle. I don’t have a...

Arias 7-1 forged blower pistons
Crane hydraulic cam, unknown specs, but said it was mild
Stage V aluminum heads...
I have 20 miles since oil change and need to replace my oil pan gasket. I’m using good, expensive oil. Can I drain it into a new clean container and reuse it? Thanks
I have a brand new cold case 26” aluminum radiator with dual 12” electric fans with shroud. New hoses, water pump, 185* thermostat. Straight distilled water with Royal Purple Water Wetter. Aluminum heads on a 426 hemi and 6-71 supercharger. Driving for 15 minutes at 9am in Hell (Arizona) it got...
I have a 68 GTX with a Weiand 6-71 blown 426 Hemi. Only 40 miles since being rebuilt. It is a 68 block with Stage V aluminum heads, Arias forged blower pistons. Everything is either new or rebuilt original parts. My question is, if I get tired of trying to see around the blower, how much could...
Anyone fab up a filler panel to cover between the grille support and radiator core support for a 68 GTX? I would like to smooth out the looks in this area. I suck at fabricating, but can make a mean cardboard template!!
I have an oil leak on my Hemi. I believe it’s coming from the oil return hole in the rear, on both heads. I have replaced heads and gaskets on SBC and BBC, but never on a Hemi. I can pull everything apart, but when I do, I need to re-install the o-ring that was done to the block and reinstall...
I got a speeding ticket on Friday for doing 85 in a 75 on the freeway. I was leading 5 cars in the fast lane, passing 4 semis. He pulled me over because I was leading the pack. Ok, I was passing and going over the speed limit, but I’ve never had a speeding ticket in my life (just never got...
Looking for a nice original woodgrain radio bezel for a 68 GTX. New aftermarket one I bought from Van’s does not match the original woodgrain and is too noticeable for my likings. Thanks
I just pulled this gauge cluster from my 68 GTX and replaced it with the Dakota Digital RTX cluster. I can confirm the speedo, ammeter worked. The tach, fuel and temp gauges were not wired up when I got the car. They all look to be in good shape. Car only had 400 miles put on it in the last 46...
It’s a Holley Dominator 1050. Has been rebuilt with less than 10 miles on it. Comes with box of extra parts. I was told this may have been a NASCAR carb. Was purchased in the 70’s. I went EFI and was looking for a fair price for it. Only numbers on it are: 86490 on one side, and 12R-4325B. Thanks
I have Stage V aluminum heads with freeze plugs on each end. It has the rubber expandable plugs right now, and it will not allow my new alternator to fit. I need to take out the rubber plug and install a concave plug. Which plug should I use in aluminum? Brass, steel, copper, etc… Thanks
I have a new Powermaster 95 amp alternator with a new solid state regulator. It charges, but is erratic from 13 to 15 volts constantly. Checked at the battery, starter relay, and stud on alternator. All the same. The field wire going to the VR is anywhere from .1 to 12 volts and all in between...
