Budget 466 build, hp guesstimate.

Building a 466 flat top pistons with pro comp heads ( otb) 1.73 Lunati rocker arms, EDL-7167 cam kit 7166 intake with Holley 850 dbl. pump long tube headers.c6 3500 stall 3.70 gears .msd ignition.

Will it make 400 hp or more ? Thanks Whitefield

not an engine builder. but when I put a 466 together I wished I had not bought the rpm intake. the torker II proved to be a better choice. fwiw. bob

Got the intake used for 125 bucks. Wanted a stealth!
Also that is interesting info about the intakes .
Thanks for the intake info

I'd say yes, it will make 400, but what is the compression ratio??, what are the cam specs??

Whitefield it should make over 400 hp in my opinion .That #7167 cam is 234-244 556-581 on a 108 ls If I remember correctly edelbrock advertised that with their heads (big chamber I believe ) and the #7167 camshaft over 500 hp your pro comp heads probably flow about the same as edelbrocks so your hp estimate is really conservative .You probably are aware of this but make sure to get your pistons to deck height as close to zero as possible .Doug rendeer

The outbid the box procomps don't flo as good as the eddys do out of the box.

I agree ! If we do make 400 hp or a tick over we will probably spray it with 150hp NOS

Going in a pick up truck street weekend good weather driver .

I haven't done the math but I am guessing the compression will be around 10.5:1
Cam spec

I afraid more like 9.5 if its the large chamber ones(not milled down) alot come in mid 80s but are like milled a bunch. I milled .80 off a set for a 528 I built for a buddy and they sealed great at around 12 to one with a flattop. Short turn really needs widend bad atleast, sometimes the ssr is angle wrong too. Easy 300 cfm after that's corrected with the 2.08 valve. They max out around 350 with big valve. Don't lower the crest of SSR any! Got pics if ya decide to warm them over with a grinder..,ED

I think you mean .080" not .80" as that would be impossible without making the head unusable junk. Razz

I figure with zero deck and surface the heads to get a 84 cc 82 cc combustion chamber and the srp flat top pistons would get us close to 10.5:1. I don't have all of the parts here to measure to do the math with to know for sure. we will be happy with what ever we end up with. ! bounce

I would like those pics . pm me . thanks Whitefield

ED468 December 27th 2017, 9:05 pm

Please Pm me a email, takes me a hr to figure out how to send pics on here and always forget since its like once a yr Smile

Thanks..,ED

We got most of the part from the machine shop this week and plan on starting the build Saturday. We are shooting for maybe some 7:50 1/8 mile times on motor. thanks Whitefield

Way back around 2000, Ford Racing sold a crate motor M-6007-E460 which was similar to that. The differences were that it had A429 heads and an A443 camshaft; (which has the same specs as the Edelbrock cam except the separation was 112 instead of 108).

That engine made 486 horsepower with an 850 Holley 4781 carb and 2" dyno headers.

When you say out of the box...

Valve size?
Valve job as delivered from source?
Source?
Bowls and choke point as machined from PC or did supplier open up and do a proper valve job?

I've had several sets of "large valve" PC heads, sourced from an Ebay seller, come in that had 2.19" / 1.71" valves sitting on seats cut for 2.08" / 1.65" valves. Of course the valves were sitting notably high into the chamber.
The bowls in the PC heads are small even for small valves...

The flow rates were less on the intake side than OEM passenger car iron.

The heads are at the machine shop getting valve job checked and repaired if needed , spring pressure checked , and screw in studs and guide plates installed . Thank you for pointing that out about the flow . Do you have any pics of what needs to be done on the heads to make them flow closer or better than stock ? Thanks Whitefield

This has happen to my budget build.Thanks for the info!

Quite a few years ago I built a .030 over 390 (I know different engine but still Ford) I put flat tops in it and an old pair of 406 heads that had terrible flow numbers but they were what I had. I put a used flat tappet cam in it (50.00) bought from a friend. A modified Edelbrock streetmaster and Holley 750 vacumn secondary carb. This thing was VERY low buck. It made 423 hp na and we sprayed it on the dyno with a 150 hit. That was fun as it made 570 ft lb's of torque and I can assure you that you will have more than 400 hp with this 385 series. Very Happy
