You didn't specify which fuel you plan to use, but if you have not picked up the injectors yet, I would recommend getting bigger than what you have listed. 1000cc injectors with all you have listed will definitely hold you back power wise. My .02 worth.

Kevin Troy

I forgot to mention, regular pump gas fuel, 100oct here in EU
thanks for the tip for the injectors

100 ron? or 100 AKI?

Ron

btw, exhaust us full open 80mm (3,5")

You'll probably be very comparable to US 93 octane fuel because we use the AKI number. Maybe a little better. I know TScomp has plenty of those results floating around if you do a quick search. Found one for you with 93 octane results.

very good results for an unported head and stock intake
Tom dose a real good job

You could go lighter on those rods. R&R makes an I beam that is almost 80 grams lighter. I think it's 605 or 615 grams.

Black, if pushed, is good for 700+ horsepower on E85 (more if going crazy). The stoker will let you spool that thing around 4000 to 4200 rpms, depending on how everything nets out.

And if you are going to run E85 or higher octane, you can run higher compression than the 8.5.

Kevin Troy

Thanks for the info!
Where I live E85 is not available as it is in the US
Therefore, it will be 100 RON.

So, talking numbers with this current setup realistic would be around 500WHP and 600NM tq?

Also, depending on what your engine builder wants to do, both OEM and Cosworth make different sized rod and main bearings. Food for thought.

And the GSC R2 cams will give you more than the Kelfords. They're kind perfect for the build that you're doing.
