Engine combo... need some advice please

Ok, still in the research phase of my engine build for my 1303 (daily driving, Auto-X racing). I only have a $1500 budget to work from for parts (long block, exaust and carbs).

This is what i have came up with so far...

-94mm P/C
-69mm C/W crank (is cast going to be fine for under 5000 rpm?)
-Eagle w-120 cam (or like it from Scat)
-40mm/35.5mm heads from CIP-1 (s.s. valves)
-Weber 40mm IDA dual carbs (or would 44mm be better?)
-Exaust is still up in the air, what should i look for?

I was thinking about geting the Scat Engine kit that includes, P/C, C/W crank, cam (20, 25, 30, 35 scat grind option), HD oil pump, lifters, bearings, gasket kit, coneting rods. and then geting the other little things i need like push rods and tubes, full flow parts, intake and exaust... the Scat kit i have seen for $520 bucks online.

I calculated it out and it came to be around 1,300-1,400 bucks with including carbs.

Any ways, what should i get for push rods, full flow parts. What kind of comp should i run (how can i get a desired comp any ways?)?

This is my first engine build, i need all the help i can get!

Thanks!
Jonathan

Don't forget about the labor costs of having your case and heads machined for the larger cylinders and special tools for engine assembly.

I'm not sure, but I think that the Scat kit uses a cast crank.

The stock crank is forged, because when Ferdinand was designing the engine they found that the cast cranks had the fault of snapping after spirited use. Therefore, since you said you want to use your car for Auto-X, I would stay away from the cast crank and buy a forged. From what I hear, CB Performance now makes 76mm forged cranks for the same cost as a 69mm. So for maximum displacement on a budget that is what I would go with.

I think the stock crank is forged. The scat cast crank is supposed to be good for 5,500 rpm and 125hp.
