Share your engine combination............

Maybe this could become a sticky.

I've been surfing the internet and mainly magazine articles on various engine builds from a 289/302 up to a 427 windsor stroker and even a few 427FE builds.

I was just wondering if people would share their engine builds along with their HP/TQ dyno results. Thanks.

My build plans are take my 1970 351W, stroke to 408, AFR Renegade 195cc heads, @10 to 1 compression, roller cam with specs of @ .550 lift, 236/244 duration on a 112 centerline, Edelbrock AirGap or similar intake with a Holley 950HP carb. Hoping for @525 hp and 500lb.ft. of torque.

Phil,


Mine is a Ford Racing M-6007-D392E crate motor circa 2006, with Weber 48IDA induction and MSD 6A ignition. Specs are shown below. Not too dissimilar to your target specs, but nowhere near your target HP/TQ numbers. Should be helpful to you as a basis for comparison.

Cam I'm looking at is a bit more aggressive and heads I'm looking at flow about 18% more. That may be what pushes mine higher. But sounds like a solid engine. I'm hoping that what I build will last a long time. I don't relish the though of having to pull it out every year or two to be freshened up.

I'm curious what intake people use if they go with a Holley 4-barrel for fuel delivery. A simple Edelbrock dual plane or an airgap or a single plane like a Victor Jr???
 
Mine is a 302 with a mild cam, aftermarket rods and pistons, Edlebrock Ali heads, electric water pump, MSD ignition package, fuel injection, hooked to an Audi o1e. Mild power but reliable and should look nice.

More to think about. A new dual sync dist. from Holley just came to market, a low profile that will work with Borla 8 stack and fit under the fuel rails, part #565-111.
 
The only thing that's really holding me back on an 8-stack is the $7500 cost. And having real Webers is a $4000 option. Whereas a standard carb/intake is about $1000.

I have an era with a svo 302 10-1.stroked to 331 solid crowler cam, crowler rods and crank roller valve train dart iron heads and an 8 stack. dyno at 397 at 6000 rpm, the motor will spin 6500 to 7000. The motor lives at 3500 to 4000 rmp all day long and throttle response is excellent. Now my cobra which i sold a year ago very well built with a 66 427 engine, alum head dual quad 12 to 1, 5 speed, the car would pull like a freight train and you knew that there was something under the hood. All in all getting big horse power from a motor is not inexpensive but comes with costs. the gt always runs cool even in the heat and the cobra you had to keep on moving or you would watch the temp gauge go up and up. love the 8 stack for the look but the response is great and it is not electronic, just dialed in. At the end of the day I will take the small block again. Best of luck build it the way you want and dont skimp if you can afford not to as you will probably only do this once.

There's a range for multi-port/8-stack type injection....ranging from a low of about $3,500 all up to somewhat over the $7,500 you mentioned. Range just depends upon how much set up and install work you want to do yourself.

Well! I do like to read about all these strokerisms --been there and done that
and now with my basic mild performing 302W I know that by travelling on a highway at the speed limit for say, 100 miles I will get there at exactly the same time as a megadollar motor -- a bit cheaper on fuel and nothing to fix or analyse at the end :blank:

I went with something "adequate" and while it might not induce racing pulses amongst this demographic, I am quite happy with it in practice. Ford Crate motor with Edelbrock Pro-Flow EFI and ZF -2 box. Everything works extremely well together. Only(?) ~350hp but starts on first crank, idles smoothly, runs at 185°, and puts a smile on my face... What more could I ask for? Oh yeah- I also get over 20mpg in a mixed use cycle (did a 1000 mile weekend, put in ~47g of fuel; ~750m freeway, ~250m twisties).

M-6007-XB3* B303 Camshaft – Manual Transmission M-6007-XE3* E303 Camshaft
  • 302 cu. in.
  • 345 HP with M-6250-B303, 340 with M-6250-E303 camshaft, Ford Racing induction kit, headers, and a 65mm throttle body not included
  • 9.0:1 compression ratio (Nominal)
  • Ford Racing aluminum GT-40 cylinder heads M-6049-X303 and GT-40 valve train
  • Ford Racing high performance hydraulic roller camshaft M-6250-B303 (M-6007-XB3), and M-6250-E303 (M-6007-XE3) roller lifters and standard rocker arms
 
Phillip....

I'm doing an FE for a MK2 but I can help out on 351w strokers.

Stock block,4.170 crank,dished pistons,Vic Jr's out of the box,Super Victor intake and
the biggest Crane hydraulic roller,950HP....Ran this combo for almost 60K miles.
Kept the revs under 6500 rpm.

Roughly 410-430 rwhp on 4 different dynos. Plenty of torque.

Got bored (it's in a Unique Motorcars Cobra). Installed solid roller. Heads ported,bigger
valves,carb work....7500 rpm,lots of power,10K miles of fun, then the stock block died from excessive main cap walk. 460-470 rwhp depending on the day.

Now....Dart block,454 stroker kit, more compression,more cam,same top end. It really needs a set of Glidden Victor 2's/or other monster head and bigger intake. No idea on the current power,while fun,it just isn't quite enough (maybe 500ish to the rear wheels?).

I'll get flamed for this but....It's really hard to put to big of a 20 degree head on a stroker. I built my first stroker almost 20 years ago. Knowing what I know now,I wouldn't put anything less than a 225 AFR on something bigger than 400 inches....but hey that's me! Then again I'm also the guy who thinks a 530 inch FE will be just about right in a MK2....

Total disclaimer....I've been wrenching on cars as a living for over 25 years so engine stuff is second nature to me. Your individual results may vary....

Hi Chris, nice sounding combos. As far as the bottom end, I have been told that a bottom end girdle would be a very good idea and increases rigidity by about 40%. So that's in the plan. As far as the heads and cam, I have been told by several to keep the intake ports to 195 or 205 at most and a "mild" roller cam (234/244 duration with @.550 lift on a 112 centerline) to have lots of torque and to keep it under 6500 rpm's and everything should be fine for a long time. I would probably top it off with either an AirGap and 950HP or go for the Webers.

Here's one of the article's I read and am using as a guide to my final build: Bob Lathrop's Modest 351 Windsor - Hot Rod Network
