The 64 heads also are probably the super small heart shaped combustion chamber. You wouldn't want that bump in compression.
Hardened seats are the deal breaker here. The cost to upgrade the 64 heads is more than it's worth.
As far as victor intake... What's your goal. A perf rpm will rev to 6k without a loss in low end.
I knew y'all were going to say that . They are the small chamber , but they had just been done . Hardened seats and three angle valve job . Picked them up for a hundred .
My angle with the Vic Jr is my truck is light in the rear and I want to hook then get gone .
I am trying to copy a Sherman design 347 .
Comp cams told me I would need to run a 280 . Its in an email they sent when I contacted them about matching one up to what I was planning on doing . 4.11 gears and 3000 stall.
Well if you want a motor that makies power from 3000-6000rpm then you need MUCH bigger heads than either of these. If however you want to make use of the heads that are available to you then you need to back down the cam and converter to a 260 and 1500 stall and keep the motor under 5000rpm.
Most Ford V8 auto transmissions shift ~5,000-5,500 rpm at full throttle (depending) so building an engine to make peak HP right in that range should work best.
In stock application yes...
My 4r70 shifts at 6500, my e4od will shift at 6k full throttle, my 460 barely makes it past 5k stock. My c6 shifts at 6800.
It really depends on how the trans is setup, or programmed to shift at.
If you're carb, then a c6 or c4 will shift where you want it to, according to how it's rebuilt.
It will be carbed and i will use a c6. I am not new to building engines , restorations , rods or bracket racing . Its what my dad and grandfather did . They had a , back then it was called a service station and a body shop. I have been away for awhile though. I have always been intrigued by Joe Sherman and his engine builds. He reminds me of the old hot rodders i knew growing up. They had a great understanding of things . Knew what they needed or the end result to be , used what they had or could get easily and made it better. They didnt just open a catalog and order bolt on speed . Sherman reminds me of these old guys. Seems today everybody just bolts things on . Here is an example of what i am going to copy . 400 hp 302 Small-Block - Mustang & Fords Magazine
I am honestly building this truck on a bet . I was bet I couldn't build a vehicle that would run on the street and run mid 7's on the track for less than 4k. I also can't buy things from people I know for cheap as a favor .
I also had to buy the vehicle mind you.
I bought the 289 heads for only a hundred . I will have them ported.
I have 3k left to spend .
Thanks again for all your help
Is it going to be an f100 or f150 truck, or a ranger...
Start stripping it down to nothing.
I hope you're talking 7s in the 1/8 mile, cause you're gonna need a fair amount of nitrous if you're talking 1/4.
Porting and bigger valves will be key, those 64 heads are not what Sherman used, I bet he had bigger valves and some very extensive porting done.
If you had a good trans to start with, I'd get a 3-3200 stall. Don't go too high unless you're really set on a hp level. More hp the higher it will stall. So 3k stall with 350hp will be 3500 with 400hp. Or something close.
Its an f100 flareside and I did forget to mention it is in the 1/8 th. I picked up another 302 block for $25. I am going to sell the one that is in it . It runs good , doesn't smoke nor leak oil. That will give me a bit more money to play with. I just today picked up a 6al box for 50.
I am in parts trading mode. Buying and selling to get what I want or need.
I really believe this is within reality.
Joe is definitely old school, that's for sure. It would be nice if that article went into how he worked the heads. He used to post over on the Ford Muscle board and they've got a dyno board with plenty of engine specs and dyno results. Definitely worth a look if you haven't checked it out.
