Holley has the new 900 cfm Xflow out so we got one to test. Ran it on a 505 inch big block and made right at 700 hp. This is a pump gas engine with Trick Flow 270 heads, a Comp street roller cam and a ported Indy intake.

An article I did for Hot Rod: Adding Holley’s Universal Coil-Near-Plug Ignition System to a Big-Block Mopar - Hot Rod Network This was a 514 inch big block that made around 900 hp depending on which parts we were testing. This was the final test I ran with that engine. Engine was sold earlier...

Just got my new SCAT superlight crank. This is an RB crank with 4.250 stroke and 8 bolt flange. It weighs 64 lbs which is about 5 or 6 lbs lighter than usual. Nice looking crank, I like the extra features on the superlight version.

Finished up the dyno testing using the dual conical valve springs on my low deck 470. This engine has the Trick Flow 270 heads and a big solid roller cam. Everything worked great and we made around 750 hp at 7000 rpm. The springs worked just fine with the super aggressive solid roller cam. Here...

T&D rocker arms on my low deck 470 with pushrod oiling. The internal oil passage to the heads is plugged in the block so all oil is coming up the pushrods. It really flows a lot of oil, more than I expected.

I'm gradually getting my price list and website updated for 2018. One of the new products I'll have in 2018 is a trigger wheel and pulley that fits with a stock water pump housing and pulley. My previous EFI trigger wheels were all designed for race engines with Jesel belt drives since that is...

My '72 Duster has small bolt pattern disc brakes on it as well as new Centerlines and tires. But, the old style center link comes out up rather than down. That doesn't work with the TTi headers so I'm thinking of swapping over to the '73 style center link which drops out down. So is it possible...

Here is the latest dyno test article with my pump gas 470. In this article I tested a belt driven oil pump as well as a vacuum pump. Peak power was 775 hp on unleaded pump gas. The Wilson porting helped out a bunch as did the vacuum pump. With this kind of power you should be able to drive to...

Had a 470 low deck on the dyno last week. This is a pump gas engine running unleaded premium. Trick Flow 270 heads, Indy 400-3 intake that was ported by Wilson, solid roller cam and some good parts such as Moroso dragster pan, Jesel front drive setup, T&D rocker arms. The heads are out of the...

Holley HP EFI Install - Hot Rod Network 900 hp Mopar big block with EFI. Should be a nice engine for an A body!

I have this '72 Duster that has been sitting in my shop collecting dust for 5 years. I picked it up from a friend of mine who hit some tough times but I just never had much time to work on it. I put it up for sale on Craigslist for $4900 which I thought was a super good price but not a single...

Just finished up the first set of brackets to hang smart coils above the plugs on a big block. This will allow me to get rid of the big MSD 7AL box as well as the MSD coil and the Jesel distributor. I've heard that the engines run a lot better with CnP, guess I'll find out shortly.

Just finished a couple days of dyno testing on this 514 inch big block with sequential EFI. Tuning has never been so easy! We just click the mouse to change the fuel curve or the ignition timing. I'm using the Holley HP system on this engine which allows me to change the fuel by cylinder if I...

Just breaking it in on the dyno.

Had my 514 inch big block on the dyno this week. It has CNC ported EZ heads, a Super Victor with Wilson porting and a 1250 Dominator. We were testing different race fuels. The Q16 made the most power with just a hair over 900 hp. I'll post a couple of pictures and a link to a video.

I had this pan made from a solid block of aluminum. I think the block weighed about 90 lbs to start with. I haven't bolted it on yet but should get to it shortly.

Two piece valve cover with a clear top to see how the oiling system is working.
