Who Builds FORD Nascar Engines?

XCSEDAN · 16-08-2007, 10:27 PM

Hey
i was a little unsure where to post this, in the pits or here or an engine section.
i figured here as it would see the most traffic

(hopefully that's ok?)

I was wonder who makes the FORD Nascar Engines, i know Arrington make a the R5P7 Race Engine but thats a Chrysler engine....
i'm pretty sure Roush makes them, but i can't find a site that lets you look at their actual race engines.... (unlike Arrington who actually sell them!!!)

does anyone have any info on who makes the Ford Nascar Engines???

Cheers

All NASCAR engines start out with a factory block and the teams take it from there.
Rouch Performance http://www.roushperf.com/ do the engines for Jack Rouch's teams http://www.roushracing.com/

I'm not sure if others like Ambrose's team http://www.woodbrothersjtg.com/ do their own or are supplied by Rouch.

They all pretty much make their own to a control formula, Ford Racing Yates heads, Ford Racing SVO block etc... over 820HP from 357 ci for the Nextel cup cars (without restrictor plates).

thanks guys!
geez i wish i had foxtel, i love hearing those things rev!!! they just sit at 8000+rpm all day no problems at all....

Yeah no problems at all because they get fully rebuilt after every meet.

yeah i know that, but most serious race engines do.
but still, the torture that those motors put up with is amazing!
i dont know of many other engines that hold together that well,
8000+rpm for a few hours is a long time, its constant if there is no safety flag or anything like that (apart from pit stops).

ummmm.... no i haven't not in the last five years.... last time i watched Dale Earnhardt (RIP) was winning the race! (that shows you how long its been)
didn't know they were that touchy now....

Yep, they go around at far less than 8k rpm a lot of the time. The sponsors sure get value for their money!

ebxr88240 is right about boat engine builders

Ive meet this guy who swears by this engine boat builder but its very expensive as well.

Skirace race engines get as hard a time as anything i know of, racing a boat is like driving up a hill under full load and never getting to the top, the continuous and relentless loads and abnormal harmonics are extreme and destroy engines...

Years ago was in a ski boat with Chevy 500 ci big block.. At 7500 rpm it threw a leg out of bed and I was right beside it... Frightened the life out of me!!!
This all came back the other day when a turbo 4AGZE engine was on dyno.. Pulling 9500 at 25 Lb boost making 240+ wkw ... It didn't let go though!!!
Oh the ski boat!!! I had to put my life jacket in the hole the rod made or we would have sunk...It was Spinner Blacks boat from Morrinsville N.Z...
