If you are wanting big block displacment, you may think about a Dart 351 block. It is a Ford small block so all the headers, heads, intakes, cams, accessories, etc that fit a Windsor fit that, but you can bore and stroke it to 383, 393, 409, or even 454 CID without issues. Big block displacment with small block accessibility! I too looked at 390, 427s, 428s, and 429s before deciding on a 383 stroker. I make as much torque with that (although a little higher in the band) as a stock 429, but can rev to 7k giving me much more horesepower without the big block headaches. The lowend torque of a 429 is not very usable in a small musclecar. If you use the lowend torque, you will never get the tires to stick. The 390 and 428 are a little more useful with torque peaking at 5400 vs. the 3800rpm of the 429. If you really want a big block, I would go with a 428, but think about a Dart stroker.

The 429 cobrajet was introduced into the Mustang in 1969, I think. The FE 428 had been in them since the Shelby in '67. In '69 and '70 you could get either a 428 or 429. In '71 they stopped putting FEs in the Mustang. I guess this was a fundamental shift away from the FE platform and to the Ford 385 plateform which eventually became the 460. As someone said above, the Ford 385 family of engines were basically truck engines. By that point, I guess Ford has given up on performance big blocks in small cars. The Boss 429 was a knee jerk answer to the Hemi, and was really only made to get the 429 into NASCAR. I am not sure why the Ford NASCAR teams want the switch from the 427 to the 429. To me, the FE big block line made much more sense for the Mustang. Maybe you could tweak the 429 cam and heads to run better than a 428, but I really do not know much about the ins and outs ford big blocks.

i saw a 427 SOHC in a 63 galaxie at a car show last week. i love that motor too. he had that motor since 1975 when he bought it for $500!!!!!!!!!!!

i want a 429 Boss, 426 Hemi, 427 SOHC, 409, and turn my 460 into a 521 stroker.

these are not neccesarily realities, just dreams. so please save it.

if your not into too much power, just go for it.

I like the idea of a Dart 351 small block over bored to a 383, 393, 409, or even 454. Any recomendations when looking for someone to do the boring? What does this usually cost.

PS. I like power!!!

The machining is going to be a minor expense in building a stroker out of a Dart block. Boring, honing, and cleaning up should not cost more than $500-750. The heads, block, and rotating assembly are the big expenses. With a Dart 351, uses a Cleveland crank with the smaller mains to reduce friction. You can actually get the Dart 351 in a Cleveland or Windsor deck height, but you will probably want the 9.5 Windsor deck so you can have access to the many Windsor aftermarket parts. Keep that in mind when you go shopping for a rotating assembly. Scat and Eagle make Dart Ford smallblock crank and rod assemblies, but you will need to get custom pistons made for the compression ratio you want to run. Lets just say the Dart stroker is more custom than other strokers, but you will be getting a bullet proof foundation! A Dart engine is a pretty serious project, but it is capable of huge power and still hold together for a street machine. The best part is it uses Ford 351 parts, so heads, cams, headers, etc. are easy to find and you do not have clearance issues under the hood.

That sound like what I want. Do you have a build thread on the forum?

Why not use a old 351W?

Did you use the Iron Egale Sportsman, the Iron Egale or the Aluminum?

Thanks
Joe
