    The coupe only weighs about 2700 pounds . Makes for a fun drive.

    We don’t have a lot of context about this build. Also if that’s at the wheels or crank power.

    Hopefully it exceeds your goals!

    Sorry, It is rear wheel horsepower . I always wanted to do a Windsor build and my wife got a good Christmas bonus in 2016 so I ordered the Scat 408 kit .The car had already had 351 Windsor in it with vic jr heads and 282 comp cam. So I used the parts already had and got her running . 35 spline axles 4:10 gears and TKO 500. Name:  IMG_0605.jpg

    I got the heads , cam and roller rockers for $ 900. So I've tried to keep it a budget build . I eventually will get the heads cnc ported and get rid of the baby cam.

    That should be a lot of fun!

    Iím shooting for around 400 at the crank N/A out of the motor for my Saleen build.

    The shortblock + rotating assembly and block I have right now needs to get checked out. It appears to be a 308 CID (0.040 over) roller motor. The a-hole that sold it to me lied about what it was. He advertised it as a 30K mile OE 302HO motor from his grandpas wrecked 1990. Not so much... needless to say I now call bull**** on everything and demand receipts or pulling the pan and heads for inspection. Sucks a person has to be this way.

    i was shooting for 11.5-12:1 compression, the valve reliefs are so huge Iíll be lucky to get 9.

    If the block turns out to be crap too I may just build a 4.125 bore and 3.25 stroke 347 in a boss block or even say screw it an go up to a 363. Or a 351W based stroker build... grr...

    Ive seen AFR 185ís on a 408 turn in a 650HP/torque N/A trim at the crank dyno sheet with an aggressive cam. Not going to lie - such a build is tempting. So is a 427....

    the torque you get with the strokers is just a blast. I would stroke it if you have the funds .

    Funds are not of major concern.

    Too much low end “stump pulling” “tire frying” torque has zero benefits and a lot of drawbacks on a fox on the street, the dragsteip, or in SCCA situations.

    I’ve spent a lot of money already on my car ditching low end torque in favor of being able to rev so it gains mid and high RPM power. Watching an overpowered car go up in tire smoke is best enjoyed from the rear view mirror......

    But yes - for romping around strokers (and supercharger) are the bomb. Instant power.

    For the high rpm stuff the mod motor stuff is nice. My 2004 Mach 1 made 388 rwhp with custom cams at 6950 rpm . Where my 408 does at 5900rpm . The 4v motors are just so smooth though.

    Refreshed the motor with new rings and Lunati 61013 cam . New springs in the heads and some head work. Took her to the track and didn't get a clean pass in oh well.
    Came out and made one pass at a measly 3000 rpm launch . The motor noised over and almost shut off on the 1-2 shift . pulled over and checked and popped the hood and my buddy peanut noticed the spark was jumping out of the number 1 plug and arcing out on the head. The porcelain had cracked on the plug . Also fuel pressure was only 3 psi . Surprised she got air on the low rpm launch .Name:  coupe air.jpg

    Nice launch. Hope to see it with the kinks ironed out.

    Well finally starting to dial it in . DA was still 1790 above sea level but knocked off a new best of 6.88 !

    One of the things I found is the SVO 335 fully counter-weighed crank, non twist forging, basically based on the old Y block 312 forged item; lighter than those that aren't counter-weighed. The 28 ounce unbalance was a hangover from the massive weight reduction forced on, and programmed into the foundry when the Small block Engineer Stirrett did the cast iron crank 221-260-289 engines, based on some of the 238-312 Y block transfer line tooling. The 351W, and 335 series 351M/400 engines were S code 390 replacements, so Ford never really decided to spend a dime on better cranks until the NASCAR and SVO era, about 1983, with fruit in the mid 80's.


    Lots of 351 blocks crack due to the crank trying to move the mains.

    IIRC, the 1988 era SVO crank is able to be made into a 4" stroker.


    The loss of smoothness up top is of course due to air speed. Four valves per cylinder takes a lot of the sharp velocities away. The aftermarket wedge heads are smoother than canted valve alloys, so your on the right track!


    Well done!

    erratic50...post me if you want some info on making a stock 40 thou over block live with a set of hi compression AFR 185's...Ford went right through the block preservation issues when the first MCU EEC II/EEC III knock sensor Windsor 351's came out in 1980/81 on the Panther platform.

    Ford and Honda were working on detonation resistance on the 302 and 351 Windsor foundry design engines, and the real success with small blocks with alloy heads and stock blocks cones from eliminating the main bearing movement from incipient detonation. The last big hit was the 5.6 liter T3 program by ProDrive/Tickford in Australia. Downgraded to non forged 1.169" compression height pistons, plateau honed cylinder-wall USA made 5.0 Explorer block, added a crank main girdle, and 50 Oz nodular iron crank with Scat stylr 5.4" rods.

    Past the 6000 rpm limit they attached to the last factory 342 5.6 liter, then you've gotta look at how the 351 engines in 1969 were made.

    The bigger mains and reduced unbalance of the crank from 50 ounce to 28 already unloads the stronger 351 W and 351C and 351M/400 Ford blocks. When four bolt mins were added, the block life on even 351C's wasn't drastically improved because detonation shows itself up in main bearing cap movement.

    Buy a neutral balance 3.25 steel crank, and call me about the detonation elimination requirements rather than trying to do other changes to your AFR 185's. 8.206 and 9.469/9.500 inch tall Windsor Bill Gay ultra thin-wall foundry design engines were engines built down to a cost.

    Successfully stroking them without compromising on compression just requires a knock sensor.

    Adding alloy heads removes bending resistance strength in the block, and any cast nodular iron crank with small diameter main bearings, Detroit 28 or 50 oz unbalance and high compression ratios is asking for block bulkhead and web failure.

    Sooooo, Ford Motorsport SVO made the custom forged undressed crank blank in the mid eighties for TransAm 302s and NASCAR 351s. It won't bend as much if prepared properly. If it does bend, a steel crank will ruin a block just the same, but if bending is kept down, a borderline block should be preserved.

    Detonation resistance was taken care of by a few people who worked on the PROCO engine program, only a couple of people have talked about how a stock Cleveland plant iron block behaves under detonation.

    I've got some info for you if you don't want to downgrade your compression ratio and still stroke out an over-bored 5.0 block. Some big fat 4.185 capable Felpro 1031L and 1031R's also work to reduce compression on smaller 4" bore engines.
