My friend put together a motor and now he is selling because he lost intrest. Here is the specs: It has never been fired and was built by Reids automotive in Whitman MA.
355,stock crank,Eagle Sir rods, TRW flatop pistons, Roller rockers,comp cams rollercam, (dont know specs but I think it is 220 or so at .050) AFR 195 heads, A whole Edelbrock intake system runners manifold Holly 58 mmTB and 36lb injectors. All parts are new, also a Heavy duty flexplate and stock oem balancer. Crome valve covers, double roller chain. and Moroso 6qt pan. Compression is 9.1 because he was going to run a small supercharger on it. The motor comes with everything Fuel rails, adjustable regulater,plus I think Edelbrock headers. I dont know how much hp this motor will put out But he is asking $3000 for it. I know the builder he is a very reputable shop and I know he paid $4000 just for the long block.I think its a great price but the only thing I dont like is the stock crank, its kind of crutch for future mods. Any opinions are welcome .If anyone can give a hp estimate Id appreciate that too. Builder said it would put out at least 375hp at the crank, a friends simaler motor with a zz9 made 360hp and 440ftlbs torque.Thanks all

Cam is critical. You gotta know what it is.

Injectors are way too big.

If you're worried about the crank, change it now.

five7kid is right, those injectors are way to big for that motor.

The crank will be fine w/ that setup IMO, but if you are worried change it now while you can.

I think the injectors were 36lbs because my friend was going to run a small supercharger on it. Ill be getting the cam specs and when I do Ill post them.Thanks again

Here are the cam specs,supposidly they are set up for a blower. .500 intake .510 exhaust 114 lobe dont have the duration though. Any thoughts?this motor worth it?thanks

I would say that either the cam specs that he gave you are wrong, or he is full of crap. especially if there are only 195 heads on it, with a .500 lift cam those heads wont make much power, and if he built it for a blower, why diddnt he get bigger heads to accomidate the new flow charistics? I just got dont building a 350 for my truck, and including the engine ( 4 bolt) I only have like $1300, and thats including headders, and a new ignition system. I say build your own engine, take out all of the guess work, and have fun at it while youdo it. Besides if you do it you will know that its a good job. BTW the motor I put in my truck makes about 350 HP, and around 400 foot pounds. and just so you know the ZZ4 motor is a engine that is designed around itself, everything is made for it, not just random parts thrown together, ie, the cam and heads are designed spacifically for that application, and thats why it makes what it does, not the sheer displacement, but rather a combination of superior matching parts, and hours upon hours of dyno testing by GM. just my $.02 but I say do it your self, and build a bad whamma jamma, and KNOW what is it it, not just guess work.

I dont understand? Why would 500 lift will not make much power with 195 heads?This is a TPI motor. Its much more expensive to build then your carb motor. To build this motor on my own would cost me over $4500 without the intake,tb and injectors it has on it,which would add another $1200 easy.I think its a good deal.But I really need to hear from TPI owners

Seems like a pretty good deal to me. When you figure in buying a new rebuilt roller shortblock, AFR 195 heads, plus a whole upgraded TPI setup you would come out way higher than $3k. And this sounds like a pretty complete setup too, stuff like the flexplate, valve covers, roller rockers etc adds up quick, if it's got headers too then excellent. Who gives a rats *** if the cam isn't ideal, swap it the heck out... And if the injectors are too big sell em and snag some more suitable. Only downside I see is the compression is a little lower than you'd like, but it will still make some good power... Does it come with a custom computer chip tune to match the setup? If so even better...

1. Good deal.
2. Crappy combo.

I'd buy it, but don't stick it in untouched.

I don't think the cam is too big either, but damn, you need to change that intake manifold. It's a tiny step up from a stock TPI manifold, and will start to seriously impede power before the 300 HP mark. Long tube runner intakes are NOT the answer for a performance build. I'd move to a stealth ram, or perhaps even a DFI setup on a converted single plane carb manifold. You can sell the edelbrock crap and pay for either of those (or at least come close).

I don't really see a problem with the stock crank. Should be ok for 450~hp, which it seems enough to hold what you've got. Or, just sell the edelbrock, get a stealth ram for 400 bucks, and spend the difference on a better crank.

Just for ****s, a friend of mine put together a simaler combo, onlyu thing differnet was the cam which was a ZZ( and the compression was 10.1 He made 360hp and 440ftlbs. I plan on running a blower on this motor.I used to have a stock motored procharger that ran 12.60 on 9lbs. I just want to run this on this motor.Im thinking the crank will be overstressed here under boost.I mostlikly will put a new crank in forged 4340 scat or gm 1053 zz4 crank.Any other input?Thanks
