Still Wont Start/Run

Ok I've had numerous problems this last year with my Bronco and I'm at my wit's end here. M My engine is newly rebuilt and I have barely had it running for more than 20-30 minutes twice.

Here is the specs of my Bronco and the engine rebuild:

OK let's start at the begining.

Does the engine crank?

I know nothing about cams, but I do recall reading on here that changing cams is much easier on MAF systems than it is on MAP systems.

Although you noted that the cam is computer compatible, does the PCM have to be reflashed/updated?

Rons Beast: The Engine does crank now, yes.

Steve83: Compression is approx. 100 per cylinder; Fuel Pressure is 40 psi; Battery voltage stays between 12-12v.

BroncoJoe19: .....I'm not sure at this point. The cam specs are about the same as they were OEM (actually I think the factory cam was larger)

I'm thinking about tearing it all down and redoing it all

 

[Rons beast]

Ok ..it cranks

while it's cranking does it have spark?

Does it get fuel?

 

[cpratt1999]

Yes to both. At least it did. I was thinking that the plug wires might have gotten some residual oil on them while I was adjusting the valves. Ill pull em in the am to know for sure.

 

[cpratt1999]

Thanks for your help gang

 

[cpratt1999]

You know....I may have had the valves over adjusted

You know....I may have had the valves over adjusted

Please correct me if I'm wrong but doesn't the ford engines have a torque spec for rocker arm adjustment

After further research I discovered that not only were the heads different in years, but they also had completely different cc ratings, and even had completely different intake/exhaust valve sizes. Both were for 302 engines which can be used on the 351W with modification, but with the other mechanical differences they are completely incompatible.

I have attempted to contact the seller several times hoping to resolve the problem and obtain the correct heads. I attempted contact via internet and phonecalls over the last 2 YEARS and never once have they even tried to even take the time to lie to me again. They refuse my calls and messages. Clearly I had been robbed of over $370, and they have no intentions to maintain accountability.

I have also discovered that this last year several others have been ripped off, filed claims and attempted to rectify the problem with no solution. The BBB website gives them an F rating, and they mention that ADC has repeatedly failed to provide legitimate proof that they are a legitimate business. The only thing keeping them from being sued for credit card fraud and internet scamming is the fact that they send you something to complete the erroneous transactions. Good luck even finding them online anymore, they've packed their bags and moved on to other scams.
