Here is a little 383 chev we just finished doing a refresh on for a customer up the mountains. Used his original block went out to 040 on the bore, changed it to 6 inch rods and forged pistons now with 11:1 comp. Used his original trick flow heads and set them up for hydraulic roller, upgraded the rocker gear to 7/16 stud and 1.6 rockers. We rebuilt his carb and dizzy to suit.

Should wake up the old HQ.

Here's a 427 Dart LS we finished off late last year. It has a Harrop 2650 on top running E85. The customers previous engine unfortunately lost a conrod whilst driving which took out most of the bottom end. We built up a 427 upgrade for him making 1089hp at the hubs.

Well about 4 weeks ago it seem we had experienced a power surge through our balancing machine. Considering we use this machine daily it was not a good thing. Well long story short, 2 shipments of parts out of the USA and countless thousands later happy that our machine has received a full latest upgrade to all the new software and program available. The support from the machine manufacturer in the states has been awesome trying to get us up and going asap.
Now just need to get through weeks worth of balancing.

We can now re face lifters. We purchased this old repco lifter facer in average condition late last year, we ended up doing a full refurb on it and is running mint.
If you have any lifters or buckets need facing don’t hesitate to call.

UPDATE: machine has found a new home, thanks to everyone.

If anyone is interested I am moving on a bohlm HFS-6 surface grinder. It is 3 phase, have the manuals. It is working for the most part. Does have a spindle oil leak not sure from where. Has served us well but no longer needed and can use the space for something else.

We recently had Danny Castro drop his SR20 off out of his improved production Nissan Silvia for a freshen up before the new season. The engine has done basically 2 seasons of work with racing and dyno development.
The engine was in really good condition, basically just needing bearing, new pistons as they were all cracked under the pin bosses and rod bolts.
