But will adapt directly to a Ford intake if it has FI *bosses* (female ports for the injectors)
It is a Holley 1000 CFM throttle body with 36 lb injectors, rails, and the Commander 950 computer module. Vern at WCC is currently about finished milling the (high polished aluminum) intake for the injectors. I THINK the intake we are using is the Edelbrock Performer, but truthfully I plumb fergot. It is a single plane type, with relatively low rise...the same type of intake that Holley makes standard for the 454 rat motor assembly (WHY , oh WHY Holley makes a Chevy version, and NO complete Ford 460 assembly, I do not know) I assume that we will gain about 5% HP, which would be 30 more HP...the main benefits are the better cold starts, smoother throttle response, and no need to adjucst for altitude or other factors...fire, tune in with a laptop, and forget.
The Victor JR that came with the motor (514 crate) has bosses already milled in, but would have required a larger hood scoop.
There are several (throttle body) CFM options from Holley
All I can say about plugs, is that on my motorcycles I have owned over the years, I have noticed that plugs can really make a difference in power and especially cold starts, IF you have aftermarket high output ignition. The idea of the splitfire plugs is that you get two seperated sparks, for better and more full ignition...if you have seen the MSD *live* displays at an auto store, you know that it can jump several inches with a REAL spark !
The hotter and more high performance a motor is, the more it needs a good spark. If a motor runs well, then it will run cooler than if it has ignition problems. One plug brand I NEVER use is *champion*...mostly because I have seen them last 40% of the time that an NGK (Japanese) plug does, in a hot air cooled bike motor. Good test bed ! Auto engines are more forgiving, generally.
As to HP, it's probably not much by itself, but if you have the MSD ignition, why not get all you can out of it? Again, for sure get a high output Blaster or similar coil...makes cold starts nicer, and WILL increase HP!
The only really important thing safety wise, is to make sure that the plug you choose is for your app...if it is too long, it can actually hit the piston, etc... If it's too short, it would not ignite correctly. And to get the right heat range for your motor and it's condition...for instance, a motor using some
oil should have a hotter range plug installed, to burn the
oil off better.
