Probe Forged pistions (.30 over)
'69 Windsor Heads (no porting, just freshened up)
Lunati 51014 cam

Car Craft ran an article a while back on a 400 horse carbed 5.0L engine. AFR heads, and the stock cam I think. Don't remember if the intake was a performer or rpm.

Yeah I was thinking AFR's. The 185's are the ones I got my eyes on.

I don't think you want the 185's unless you're stroking or going forced induction.

I seen people make tons of power with the 185's, it's kinda hard to pass them up.

Whats the deal with the AFR 225's ???

I'd get the AFR 185's. I've heard 400 N/A is alot easier to come by with a carb. Yeah you'll make tons on power on a 306 with AFR 185's I might get a 3 inch exhuast If I were you. I've seen EFI 306's with 185's make 400FWHP in magazines so I think you got it.
When I build my motor im going carb kinda the same set up as you. Gonna turbo it trying to save up for a Dart block or 302R?

Hey Trophy I forgot to mention about the block, it is the R302. I'm kicking my self in the ass for not spending some $ and gotten good heads. I put all this money into the motor and then I put the 351 heads on it. I built the motor myself and I didnt want to wait for the heads, now I wish I would have.

Your not messing around, are you gonna boost it or run N/A you already got the forged bottom end. Those blocks are sweet you could run 800 HP and not even sweat it.

If youve got like 10.5-11 - 1 and good healthy cam along with the 185s, i think 400 is easily attainable

I run it now N/A. I was thinking of some juice (125 shot or so) in the future but for now I'm fine. The block is a nice peice, lots of meat everywhere. The only problem was the wait on the block, like 4 months!! When I first started planing out my combo I wanted something strong that would last time...I think I went over kil... l
