The machinist I took it to, has been building engines for years! He is very trustworthy and I have seen his work, never heard anything bad about him. My family also knows him as well as my fiances family (how cool). Anyways I showed him and explained to him what had happened and he said going flat tappet isn't the end of the world, it would work just fine and the new cam would run way better than the stock roller cam on the 93's. I showed him the cam card and he is familiar with everything, he even mentioned the correct things I had to change such as the pushrods and distributor gear. I have faith this will work, God willing this will run fine with years to come with great reliability... it's all I have to say. I can relax now lol

Appears only one has a problem with that be you, has nothing to do with you and if didn't want to hear anymore on the subject I'm sure he can and will speak for himself.
Until this post I didn't direct any comment toward you, I was not talking to you, was all entirely between him and I.
And yes the decision it is up to him, no one is or has suggested otherwise.

Let's just hope all goes well, that's the most important thing as of now. Did you all check the link to the cam I posted? It says it works great with speed density and has great power for a truck. The stock roller cam didn't even have much lift, nonetheless I will be keeping my stock parts, such as the roller cam roller lifters and pushrods, oh ofcourse the spider holding them down as well as the dogbones. Thanks all!
I will post again when all is said and done...

LOL Jaime asked for opinions on the subject so I, like others before me, posted mine.

From what I could tell you kept pushing the subject of roller cam and lifters upon him when clearly he is ablwbto run that at this time but even knowing he was unablebto run that set you still insisted of pushing it. Read before comment I g it helps out greatly.

That system was the norm for years, it works no disputing that, better alternative available these days but not the end of the world if you use that one instead for whatever the reason.
Follow the installation and break in procedures to the letter make sure you use the correct oil, or oil additive, and you shouldn't have any trouble.

IMO, better to wait an extra couple of days for better parts (roller cam) than deal with adding ZDDP and power/frictional losses for the life of the engine. Flat tappets certainly aren't the "end of the world", but when you're starting with a roller cam engine, it just doesn't make much sense to take a step backwards, especially with today's oil specs.

This thread has way too much squealing high school girls drama in it. It should have read...
1) Got the wrong parts
2) Send wrong parts back and get right parts
3) Install right parts

Even tho I might not be able to return stuff because of my strict deadline, for future references a roller cam with the HO/351w firing order will run as smooth as the old 302 firing order with a batch fire system? Anyone have done it themselves and not get the information from others on the thread? tell me all you guys know regarding both firing orders on speed density. Thanks

The 351 uses the H.O. firing order with a batch fire system and it works just fine. After my tune-up last year my truck runs nice and smooth and if I drive conservatively on the highway I can get 14-15 MPG out of it with 33's.

Since I am hard headed and need to see it to believe it myself I am asking just for one thing lol... Do any of you all have both the diagrams for the injector wiring on the 302 and 351 showing the batch fired injectors wired the same? Enlighten me, thanks! PS... I want those diagrams LOL

Well I can't give you a side by side of the two showing differences because there are none. Hanes shows the EXACT same diagram for both.

I see I see, good info... since the thread keeps rolling how would this cam work on speed density? http://www.summitracing.com/parts/cc...49-8/overview/
These questions are just for future reference for me. I have heard of many ppl running this on regular speed density and while its not the smoothest nor does it deliver the best driveability with stock tune, how does it perform on a 5000lb truck with a stock mustang TQ (yes it has a swapped rebuilt mustang AOD) but is driven like its stolen most of the time. Never does this truck pull anything. It doesn't even have the spare tire nor the rear seat and its an extended cab lol. Idiot weight reduction I know haha
