I built a few 351w for the North East dirt modifies. IMO I would not use any Cleveland 351. Depending on your rules, use the best 351w you can get. (afford) Put restrictors in the oil passages that feed the lifters. (If you run a solid lifter cam) Pull the plug at the rear of the block were the oil passages crossover to feed the lifters. I believe it a 29/64 drill bit you need, tap the hole with a 7/16 14 tap , drill a .100/to.120 hole in a 7/16 14 plug, install in main feed to lifters. Next in the # 1 main bearing saddle tap and plug largest oil feed hole for the # 1 main bearing. (you can also match the oil holes in the main bearings to the block, if you want) Some guys also restrict the oil to the cam journals, they sell kits for that. Use N351 heads if rules allow, compression is your friend. Intake depends on rules. 500 2v carb call VDL carbs. Cam, tight center line 106/107 depends on the rest of your combination. Hope this helps.
We never worry about claim it, we have that worked out, besides who wants a Ford engine? Lol No we run NRCA rules. SS396 graciously provided a copy of the rules for me. We are going to run on Thunderbird Speedway, Muskogee, Oklahoma, we hope! It’s a full 1/2 mile track. Fastest track in Oklahoma. Bones
Tell you bring a Ford to the track. Didn't you see what happened when that guy brought that Ford to the Chevy fight at Mo-Kan.
Autolite 2-barrels are GREAT carbs! Easy to work on, efficient, and plentiful. I’ve had a half a dozen and they all ran good! Sent from my iPhone using The H.A.M.B. mobile app
Most classes specify a Holley by the number, the 4412 (IIRC) comes to mind. Which is what we had until it was outlawed. I later ran it on the street on a SBC.
This will get people fires up I remember the 70s when NHRA kept adding weight to Cleveland Fords in pro stock to keep Chevy competive.
Totally different deal. They weren't limited to a fairly stock 500cfm 2bbl carb and running a dual plane intake. Cleveland heads FLOW, little Holley's don't. We had a rules change when we were running our Clevor and went from being allowed to run any carb to having to run a 390cfm 4bbl race carb. Even the best race carb available ($3500 in 1994 dollars) and it fell on it's face. Engine was junk. What turned 9200 with an 980cfm carb wouldn't turn 6700 with the 390cfm carb and had absolutely no bottom end at all. Essentially a 4200-6500 power range, not great for dirt tracks. Cleveland heads need flow to work and like RPM's, he gets neither under his rules package. SPark
Shore did! But I was also at Meltdown! Hehe We’re not going to try to win the points race, just going chase and hopefully lead a few Chevys. We plan on winning some races. My friend , that owns the car is no stranger to the circle track. He has been racing since 1979 and has several track champion trophies, in various classes. We will be competitive, even with a Ford, James. ( I hope lol) Bones
The carb on the 351C2V was rated @ 350 CFM, but the direct replacement Holley (Targetmaster?) according to an article gave more HP & MPG than the OEM. carb.
Here’s my choice. Ford high performance crate engine 351 Windsor stroked to 392 cubic inches with gt40 aluminum heads roller cam rated 430 hp 450 torque backed by a 5 speed tremac moves my deuce down the road quite nicely
Just bolts up to FE bellhousing...not SBF bell 351M then cheat(stretch the rules!) anf use the 400M crank! 6sally6 OP stated the rules sez....stock "appearing" heads. Aluminum AIN'T stock appearing. World Product makes an iron head that is stock appearing and is on the same level (or better) than the GT-40 heads. Getting compression up above 9.5/10:1 can be accomplished by decking the block so the piston tops are ABOVE the deck a few thousandths. Get pistons with just TWO valve reliefs (not the standard 4) When assembling the engine have the pistons (normally) on the left bank installed on the rods right bank. Since the wrist pins on SBF are offset (to make the engine quieter on cold starts) by rotating the pistons it give a better rod angle to the crankshaft pin!! Light weight rotating assembly is your friend!!(strong too) ARP rod bolts and main stud are good insurance. Camshaft with a tight LSA 106-108* will help the torque curve to "come on" quick. Although uncontrollable wheel spin may be an issue. IF running an A/T go with a powerglide(that's right!!) They make a modification so you use a hollowed out torque converter or NO convertor at all. A valve closed engages the tranny and open disengages it! Like running with a very light Al. flywheel in a stick car. Howz that for building Outside-the-box?!! I got a heckuva story about running an illegal camshaft and NOT getting caught!!
The 351 M is a 351c with 1.100 more deck height and larger mains bores are the same and cams interchange. Like the B and RB Mopars.
If you need a driver, just let me know. If the car won't do it on it's own, I'll carry it over the finish line.
My friend, Tommy, has picked a driver. He’s supposed to be real good. Tommy, owns the car, is having the engine built in Joplin, going to build it his was and the way the builder thinks is going to work. I think we are going to have a 50/50 chance on it being a real runner. Either it will or it won’t. Alan , don’t know about driving , but come on over watch, it’ll be a good show. Bones
6.2 is the longest rod you want in your 351. We've tried up to 6.58 and they get really lazy. The 351W has the same 3" main as the 351M/400. Also the 2.31 rod bearings. You can go to an aftermarket crank and use 302 bearings in a 351W with inserts and small journal Chevy 6.2 aftermarket rods. SPark
Sounds like y'all already have your mind made up, but I'll throw in another vote for the GT40P heads. Best-flowing stock head Ford ever made. If the Clevor setup doesn't work or you get nitpicked, might be a good option. When does the season start? Muskogee isn't far from me, and I've got a cousin down there who'd probably be up to go watch some racing.
I went to the Thunderbird site, but could not find the 2019 schedule. It’s been many years since I was a regular at the track, but I remember it still being cool, sometimes almost too cool, to race. I would guess late March or early April. Bones
Hey Boneyard : Maybe the biggest "half-mile" in Oklahoma, but there are other "half-mile" tracks that are measured on the pole as well (Calistoga, anyone?), & that makes them nearly a 5/8 mile on the wall.
