Default 4 speed crate motor or rebuild?

Hey guys I have been banging my head over doing a rebuild or getting a crate motor. I've seen some nice crate motors but some of the prices are out of my league right now some of the prices are half of what I paid for my 66. I came across one in particular and the price was around 2500 to 3000 for a 302 with 325 h.p. from Tuff Dog. Has anyone ever heard of this company? and are they trustworthy?

If your not in a rush, save your money and rebuild. If your mechanically inclined, heck man you'll save a ton of money by doing it yourself. Get a reputible machine shop to do the machine work, you know a simple bore, line hone, balancing. Save enough to build a stout 306cu.in. motor, with all forged internals. It would be better, then most stroker crate motors. If it's something you want to be driving by mid spring, to early summer and you can do it yourself then do a smart rebuild. What I mean, is make sure everything you put into that motor works together. An engine is nothing but a glorified air pump, the more air in and the more air out the better it works. If you have a set of heads, that flows so much at 560 lift, your not going to put a cam in it that has 600 lift, understand where I'm trying to go with this. Most decent builds, I'm talking complete car take anywhere from four to six years. So take your time, and you'll have a nice ride that you'll be proud of, Mike SCT Tuner.

that's a thought so basically all I need to do is get a decent top-end kit and make sure crankshaft, pistons and etc. are in decent shape?

Pretty much. I would get a new crank though and depending on how much power you plan on making you may not need new heads you could get the stock ones ported. If you are going to supercharge it then you will probably want stronger pistons as well. It all depends on what you want when the motor is done.

Like everyone above has been saying... it all depends on what your plans are for the car. You would be better off, if time permits, to take the time and have the accomplishment to doing it yourself. If you have a machine shop do all of the machining then your looking at AROUND $600. That's a low figure as I spent more than that on my machining work. If your going to race it you will be spending more money on the internal parts where as you can just get a master rebuild kit from someplace like flatlanderracing.com. They have reasonably priced kits.
