    Please give your opinions on this combo

    I am assuming that you want to keep the cam you have in the motor and just upgrade around that (the short block). The 650 Holley DP, with hi-rise dual plane and tri-y headers are a great match with a 2.5" dual exhaust system. Regarding the heads I would forget about the Powerheads and go...

    Okay I have a few Questions for you guys. I just bought a 351 and I need some info.

    If you are thinking about supercharging and want 400 RWHP you better consider a good forged rotating assembly. And a good set of aftermarket cylinder heads.

    351 CLEVELAND MODS QUESTION?

    "Could anyone fill in prices and add/subtract from this list? I'd like to have a comparison between buying some used cast iron heads versus aftermarket offerings. Also to learn how much a complete set of heads are worth versus bare. " You forgot the valves......I would go with Manley...

    351 CLEVELAND MODS QUESTION?

    Exactly. That's why I said port the bowls and polish the chambers. I had my intake ports "stuffed", it actually reduced the port volume from ~240cc'c to 225cc's. Some would argue that the bottom part of the exhaust runner inside the head should be opened up, where it appears to "pinch" the...

    351 CLEVELAND MODS QUESTION?

    Great, getting the 4v adjustable valve train heads is a definite upgrade. You'll want to get roller rockers. Are you thinking solid cam? Roller? Well, you'll want to get a set of Manley one piece stainless steel valves with undercut stems and have a good three angle valve job done. New...

    351 strokeability questions

    A 351w is one of the best stroker candidates for someone on a budget. You can turn your 351W into a 393 cube engine by using your stock rods, 302 pistons and a 3.85" stroker crank ($400-$500). Just make sure to use good heads, bigger carb, bigger cam, etc.

    351 CLEVELAND MODS QUESTION?

    If you want a lot of performance, like approximately 470-490 FWHP, take a look at my sig below. It is a pretty standard route for a street /strip set-up for clevelands. 375 FWHP can be achieved with either 2v or 4v heads. I've had both and prefer the 4v, unless it is a lower performace daily...

    is 600cfm really enough?

    Real world reply..... You have a very nice set-up for a 302 and I can guarantee you that you will make more power across the board with a bigger (well tuned) carburetor. I think a 650 double pumper would be great, even a 700 if you are adventurous. As a point of reference, I had a 302 with...

    Adding more HP?

    I would put a plan together of what you want for performance first. Parts need to work together as a system in order to work well or be optimized. When you get it right the results are usually great. And you’ll save time and money in the long run. My recommendations (and I went down the same...

    Motor Delima

    Gee, you already have a rebuilt 351W? I wouldn't hesitate putting that in. Best bang for the buck and room to grow later. Put in the 351W.

    70 Mustang,351c,auto,header question

    The HookerSuper Comps are good. If you want another recommendation call Ford Power Train (FPT) in the Seattle Washington area. They specialize in headers that fit well and aren't pavement scrapers. Let me know if you want to contact them and I will look for their number.

    Would a 351c be a direct swap?

    Will 750 Demon carb fit on stock 351 Cleveland intake?

    That's good to here, I kind of suspected it could be all right. Does yours stumble or hesitate under acceleration? The “Demon” 750 is just a trick Holley carb. Did you jet down the carb to make it run well or did you just slap it on right out of the box? Again, I had a ’71 Mach 1 with a 351C 2v...

    Will 750 Demon carb fit on stock 351 Cleveland intake?

    Well, I went down to the local speed shop and my buddy bought an Edelbrock ¾” spacer made for spreadbore applications. The spacer is nicely contoured and will allow the use of the square bore Holley on the stock manifold for the time being. But the next modification will probably be a new...

    12's combo

    You can easily get 12’s with a 302, you just have to spend the money getting the right parts, and don’t forget the suspension. It might be more of a hassle on six conversion then it is worth, however. You may want to look around for a vehicle that already has a V8 and a 9 inch rear-end.

    Will 750 Demon carb fit on stock 351 Cleveland intake?

    I totally agree with you guys that this 750 Demon is too much for the stock 351 CJ. I would recommend a Holley 650 – 700 CFM Holley with vacuum secondaries on a stock application. Though I have to mention that I ran a 750 Holley double pumper on a 351C 2v engine and it loved it. After talking to...

    Help with camshaft recommendations.

    I think any of the cams would work very well. Personally, I like the spec’s on the Cam Research cam, I think that will hit your sweet spot. It should give you good power with being very streetable. 14”-15” of vacuum is a lot. However, I think the operating range you listed for the Cam research...
