Ford 378 cu in Nascar Cleveland Engine

We don’t usually get real technical on this site. We are more about the entire car and having fun with it than building the biggest engine you can. Although we do have some good friends who live to make maximum horsepower. Rick Stanton is one of those. You know him from the Boss 429 Powered Ford Talladega that is done up as a Benny Parsons tribute car and has graced the pages of Hot Rod!

Rick just sent over some dyno data on a new Ford 378 cu in Nascar Cleveland engine and set of heads he put together. These are some amazing number.

As you can see from the information below that these heads have the potential to make 785 hp. On this run the engine made 782.5 @ 8,000 rpm.

It looks and performs like a true NASCAR small block engine. It also produces HP like a NASCAR small block!

This engine is now making almost 400 (397.9) lb. ft. of tq. from the beginning of the pull peaking at 545.6 @ 7,000 rpm and still making 513.7 tq @ 8,000 rpm, with a average of 483.35 tq. from 4,000 to 8,000 rpm.

Rick said he also found you can’t trust these timing lights with the dials on them for setting timing , the one he was using at the dyno shop was off 5 degrees compared to a regular timing light.

Here is a video of the dyno during the run.

I grew up and lived in Iowa for a good portion of my life before moving to Southern California. After 20+ years we now live outside Nashville Tennessee. I have been into cars since I was old enough to remember. I don't have a brand loyalty although I do prefer American Muscle especially the 1969/1970 NASCAR Aero Cars. (Check out our other web site at site) As long as it has four wheels and an engine I get excited. Few men are lucky enough to be able to share their passion for cars with the woman they love. Fortunately, my wife, Katriana, is also a gear head and many of our activities revolve around the cars. We have a small collection that includes at least one car from each of the Big Three. It includes a Best of Show winner, a survivor, a driver with lots of patina and several others. Katrina prefers all original cars while I like to modify them so we have a few of each. When we aren't playing with cars we are out working with or showing our miniature donkeys. You can see more about that part of our lives at
