Chas a super victor will fit in a cobra with a drop down Base (a least it does in mine). I have a 461SBF in my cobra, and i am very pleased with the engine.

Brent only 500 more? Thats a good deal considering custom pistons, notching
the block, larger heads etc

Do you run a 4500? That's a tad taller than a 4150. At the time I was using my ERA for dimensions. I think the key is it will fit some Cobras with a drop base cleaner.
Brent could do well with the early Mustang/Fairlane/Galaxy guys with this. Even seen a few Fox Mustangs run easy 9's with this combo.
Brent, that 'fastest street car', 9" tire crowd could be a good venue for you.

The Dart blocks come clearanced really well. If you have to notch, it's not by much. I've found that a lot of work has to be done to the oil pump, if you use a HV pump, even with a 4" stroke.

Chas.....indeed.

Fordracing F I believe it was 559 RWHP. I am running a solid roller 268 272 Duration, 731 722 Lift (4 7 swap on firing order),112LCA.

Chas 4150 with a 1.25 drop down base. I have about 1/4 or less before it rubs.

Brent u will have to notch the block on a dart. I do not think so on a world block. Why would need to do any work on the oil pump if using a dart block (oiling is very good)?
I am using a mellings HVHP pump with oil cooler (Cold PSI 95 cold, 45 hot with 5w30). did change the spring to get the pressure i wanted but thats it (.0025 on mains and rods).

Brent thanks for taking the time to answer questions.

It just depends on what crankshaft you go with and which rod length (and type)you use as to whether notching needs to be done. There are two 4.250" crankshafts available with different counterweight sizes...one uses a 6.200" rod, the other a 6.300" rod.

The work on the HV pump comes down to clearancing it to clear the counterweight on the crank. Dart block with a Scat forged 4" crank gets quite a bit of die grinder work on the oil pump. I may look into something a little different here as I choose to run HV pumps on everything except factory rebuilds with stock pans. I think I may look into putting the cranks on a lathe and cutting the counterweights down a little or maybe use a billet pump.

Thanks PL, that's as I remember it. We shaved a Super Vic .500 as a test for Cobras and lost a small bit of torque low down but no HP.
No the World required no notching and the oil pumps were checked and sometimes touched on an edge. Same Eagle 4.250, 4.155 bore. Aluminums weighed 475 pounds w/carb, w/o water pump.

Brent i wrongly assumed you were using a 6.3 rod and that you were referring to oiling deficiency not a clearance issue. Thats what i get for posting prior to being fully awake. Sorry Brent, no more disruptions on your post.

Thanks Chas for the info (I would like to have an aluminum block)
I wish there was a Windsor head that that would flow more in .50 to .70 range. (350 range at .700 would be nice). The engine would like it.

There are several....the 225cc AFR's can be made to flow that much and I had a worked set of TFS TW-R heads that flowed about 345 @ .700".
