im looking for a power full street car. everything i've done so far has come out great. my car is ready for the 350 ive been waiting to do.

has any one ever used one of these rotating assemblies.
190078435373 item numer ebay.com

how about the heads from summit, remanufactured double humps.
SUM-152123 item number at summitracing.com

it's my first build to i dont want to F anything up.

any other info would be great my overall budget is $1500

 

how powerful of a car do you want?? there is alittle more to building a "powerful" motor than $1500.. you only listed the rotationg assembly, and heads.. you still need the block and the labor to machine(bore).. all the little things add up..


rotating assembly.: $630(shipping included)
heads: $650 plus shipping/handling
----------------------
$1280

ok i took a look at your car domain and seems you have everything i was dreading you didnt have.. but this still leaves you with only 220 for a block, machining, gaskets, etc.. all i can say, give your self at least $2k just so you wont be dissapointed from the cost.. good luck, should be a nice ride.. i'd say around 300hp-350hp.. just take your time assembling, read instructions, double check, use recommended lube/loctite where needed and be clean..

 

ive got a 95 truck block 355 allready cleaned up and .030 over, i dont want to stress on the little things i've got some cash and some parts allready. I'm really interested in the heads and rotating assembly i dont want to buy and install crap

 

to be honest, the rotating assembly looks like a good set.. the heads look pretty good.. large valves but the runners are on the small side.. all i can say, its gonna make some torque down low.. but topend will suffer a bit due to the 165cc runners.. i say go for it.. its a pretty good build for a budjet..

 

I wouldn't touch those summit heads. They're very basic and plain jane. Not a lot better than the stock heads.
I'd do vortecs first.

 

gonna be hard to build anything decent for under $1500. Good block prep is going to run $300-500 depending on the shop; Hot tank, magnaflux, Check/Correct line bore, deck, bore, hone, final wash, cam bearings, freeze plugs.

Add another $100 to recondition a factory crank assuming that it doesn't need to be ground; wash, polish, mic, check for straight, magnaflux.

Gonna need to recondition your rods or buy new. Stock rods will do the job for you or a set of Eagle I beams. Either way is going to come out pretty close $$$ wise.

Then a set of pistons. Figure on at least $200/set for something like a set of Keith Black which should be the bare minimum for any kind of performance motor.

Plus decent bearings, oil pump, gasket kit, cam, timing set.

That's not counting heads. A set of vortecs is the way to go if I were you. Pick up a used set and have them gone through. Clean/inspect, decent valves, cut guides for clearance and machine them for seals, good valve job, set of springs and retainers, machine for screw in studs.

A few words of advice, stay away from the no-name stuff like you find on ebay. Most of the time it's cheap junk made in Korea and needs a ton of machining to make it all work and in the end you still have junk. Crank journals and rod ends that are out of round, the stroke can vary between different journals, cheap rings that will rob power, the list goes on. When it comes to stuff like that you get what you pay for. Save up and do it right.

 

I agree with the vortecs! They are excellent for a budget and flow nicely
