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...

I did not build this engine, but the information listed below is what was told to me by the previous owner who had it built in the late 80's. 1968-426 original block bored .030 over 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 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 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 Stage V heads on my 426. The block was o-ringed with copper head gaskets. I have an oil leak on both sides (bottom rears) leaking. I already checked valve cover and intake gaskets, no problems there. It only leaks after the engine has been running and then shut off. It’s in the same area...

It’s a 1968 426. I bought a Milodon adjustable timing pointer because it says it fits all Mopar big block balancers. Well, not mine! Anyone seen a 4” balancer on a hemi? It has timing marks. It’s just hard to line up the pointer when it’s so far from the balancer.

68 GTX original 4 speed. I’ve attached pics. Pedal does not come up all the way, in-line with the brake pedal. It’s a good 2-3” away. I have to use my foot to bring it up. Works fine otherwise. Over center spring is there. Clutch rod has some play. How can I get this up without “little blue...

I was going to replace my MSD #8536 pro billet with Holley Hyperspark, but noticed it will not seat all the way. The MSD shaft length from seat is 3.5”, the Holley is longer at 4.125”. Are there different lengths of intermediate shafts? I really want to use the Hyperspark, but need it to seat...

I am putting a Holley Sniper on top of my blown hemi and it says it needs to read manifold vacuum from a remote source. I have these 2 ports on the back of the Crager intake. One is plugged and the other was used for blower gauge. Can I use one of these as a vacuum source and run it to the...

I had to sell my 68 GTX about 3 years ago, and now I may go get another one. My old one was a numbers matching car. I believe it had the correct partial vin on the transmission and rear of block by oil pressure line. This owner of this 68 says there was no vin identification on 68 440’s. Did...

I have a like new TCI 727 in my 68 GTX, installed by the previous owner. It has Lokar throttle and shift cables installed. My problem is it wont shift into 3rd gear until I'm about 50-60mph and if I let off a little on the throttle. 1-2 shifts fine around 20mph. Is there an adjustment on the...
