Rookie looking for some advise April 27 2003 at 5:04 PM Kenny  (no login)
from IP address 198.82.88.214
hi all. I'm 20 years old and darn glad i found this forum. I have a 1970 (i think) Cleveland 351 4V that is totally bone stock. It is in a 1969 Mach1 that i'm trying to turn into a decent little Street Car. I was wondering if any of you guys have any suggestions on reaching the 400 HP(flywheel) area (Cam, Intake(Thinking X-cellerator w/ divider insert), Carb(mech. seconds prefered), valve train parts, ignition stuff, etc). Figured I could maybe use this forum to get things right the first time instead of experimenting and spending more $$ than i have to. I'm backing it up w/ a Toploader 4 speed and a 4.11 Detroit Locker (Donated by an old parts truck at my old work). Also, any suggestions for a streetable Clutch? Thanks for the advice in advance.

the recipe April 27 2003, 5:29 PM 
 
Why do you want 400hp ?
Is this a number you picked outta thin air cause it sounded cool ?
Or is there a 1/4 mile time you want to hit as a goal.
I ask because 400hp in a car with a 2.83 ratio rear end is gonna feel like a dog.
It's all a combination of engine/tranny/rear-end.
What rear end ratio is in the car now.
To hit 400hp you will need better than factory pistons, or poof.
Tell us what you want to do with the car.

I'm in the Northern Virginia Mustang Club and Virginia Tech Car Clubs. We hold Drag days in both and I was looking for something to shine decently at the track but i could also drive on the street. I was told 400 would be a reasonable number to shoot for. Should i shoot for something smaller?

400 isnt terribly hard to attain April 27 2003, 6:34 PM 
 
4v's shouldnt be that hard to get to 400.. and if you have 4.11s in the back then you'll be fine. this is what i'd do:
-if your block isnt terribly worn, either get it honed or bored .010 or .030(i say those two because if you go .020 like i did, you're gonna have trouble finding forged pistons. my machine shop found some from badger i think for like 500 bucks...ones in .010 and .030 are a LOT cheaper, like half that price. and stay .040 or less, dont risk crackin a cylinder)
rotating assembly:
-have your crank checked out, polished, maybe cut .010/.010 if need be, oil holes chamfered.
-have your rods shot magnafluxed and shotpeened
-get some forged flat top pistons, they're not too expensive($250), and you'll need them.
-clevite 77 bearings
Valvetrain:
-have your heads mag'd and have the pedistals machined for screw in studs
-run some roller rockers, whatever brand you like... doesnt really matter.
-get some stainless 1-piece valves, a guy on ebay sells a bunch of em, ferreas, pretty cheap. about $150 w/ shipping for a set. you'll need bronze valve guides with the stainless valves, your machine shop will take care of gettin those.
-true roller timing chain, again, your choice..
-a good set of pushrods
-cam/springs: I'd go with a comp cams 280h or 292h, or something similar from whatever cam company you like. 280h has a good rep, and i'm sure the 292 performs just as well, just at a bit high rpms. run whatever springs the cam company recommends with the cam you buy.
as for exhaust, run some 1 7/8" primary headers and a 2 1/2 inch dual exhaust from that with an H pipe or X pipe.
intake:
-weiand xcellerator/edelbrock torker/holley strip dominator/parker funnelweb intake. not in that order.. i'd say parker first, dominator a close second, weiand and edelbrock thirdish. they'll all serve you well, just matters how much you want to pay!
-port stuffers are recommended for street, and you should definately get them with the funnelweb as its designed for them.
-some kind of 4v carb, in the 700cfm range. a holley double pumper would be good.
-electric fuel pump. holley blues are nice and cheap.
-windage tray in there too...
spin it to 6500 and you'll be fine

Kenny, I see that you are in No. Va. If you are looking for a reputable shop to do your machine work or anything else, give me a call at 301-246-9225. 400 dependable hp is very optainable without breaking the bank.

350 hp would be good April 27 2003, 7:00 PM 
 
You could do this with 10 to 1 compression, hydraulic cam and a edelbrock dual plane. Keep it under 6000 rpm and it will last a long time. The dual plane will make the most torque out of those 4vs. This is what you want on the street. The excellerator will be dead and never wake up those big ports. That manifold needs 11 to 1 or more compression and 7000 rpm to work.

what about the divider that Holley makes for the X-cellerator??? Isn't it supposed to make it much more streetable?

I ran that intake.. April 27 2003, 8:12 PM 
 
with the divider. It slowed my car down 2 to 3 tenths compared to the dual plane. If you have the intake off, just look at the size of those runners! Do you think the little metal plate will cure that? Sounds like you have the intake already, don't sweat it. Just buy a dual plane and experiment with both.
