To tell you guys the truth, I have another engine. I am hoping for a quick fix, but worse case, I'll swap them out and enjoy the season, and start a rebuild on this one. I'll find and post the casting no's...

Current engine in the car is:
block-1401544 seems to be another number at the end that looks like a 6, but not sure...
heads-14081045

spare engine
block-361959
heads-781

I haven't dug into either engine yet, so I don't know what I have...all I know is that the spare works....I pulled it from a drag boat I bought, so it may have some goodies in it.... I didn't want to take it apart with no reason for doing so as it would probably not be put back together and I'd have parts all over the shop...(tell me I'm wrong).....been there done it.

Now I just have to put up with the GF complaining that I spend too much time in the shop and that I love the car more then her....

Yes, somethings never change....

Food for thought: Lots of big block boat engines are cammed for reverse crank rotation. Check to make sure she spins in the right direction.

Hummmm driving in reverse, that'd be a PIA or more a pain in the neck...?

No worries, she's a standard rotation... Usually the reverse engines come out of a boat with 2 engins side by side. One screw turns one way, the other opposite in order for the boat to drive in a stirght line and not in a big circle.

thanks tho...

Default Re: 454 not running right, need help

Just saw this add and it's local. If I do have a head/valve issue I'm wondering if this would be a wise option... (for $800)

New never used BBC oval port heads with valves from Procomp.
Part number on them is PC3021-396

I've heard procomp heads arn't the best...but the price is right, even for a season or two...

whatca guys think?

LOL! Sorry man. I'm trying not to tear it down, I took a good hit buying this car, I'm now into it for over 30k..................save it, I hear it enough from the girl friend. Now I have to explain that the engine isn't quite working good enough...etc etc...

What I would like to do is simply change out the top end, and have a nice "normal" amount of power that I can live with for a weekend/nice day driver.

I have a Voodoo cam and lifters on order. The more I think about it, the more I want to change out the heads. I have a brand new 750 holly double pumper vac and another mech one I can use. Edelbrock alum intake. I'd love to run a set of aluminum heads also, for weight and flow... I think it's a good bang for the buck.

Looking and searching sounds like a set of AFR 305's would work good for this car.

summit price is $2300 and change. This motor should be good for 400+ with this combo, and would be ideal for street use.

tell me I'm wrong and that i can be happy for a lot less and spend a lot more time out of the shop....

ah, gotta love the projects...

Well it's your money, you say you don't want to tear it down, but you have a cam and lifters ordered How they gonna get in there ? You say your into it for over 30K, but then are looking at dumping another $2300 for heads. Only you can decide what is a "nice normal amount of power", but why dump money at a project when you don't even know whats wrong with it.

I'd think if you fix whats wrong first, you'd end up spending less money and have it on the road sooner. Then figure out your upgrades, tell her they are for better fuel mileage
Good luck, keep us posted.

^^^^^I agree. It's almost certain your problem is cam or heads. You've already covered the cam part with the VooDoo purchase. Why not yank the heads and get 'em fixed, a lot less money than buying new heads. JMHO.

And that's what I have you guys for. I can only listen to her for so long, but when I hear other people telling me to relax, (that know what they are talking about) then something clicks. I tend to get ahead of my self sometimes. Yes, I still plan on finding out whats wrong first rather then throwing money at an unknown problem. I agree that makes sense.All I was thinking while flopping around in bed and not sleeping for a few nights was.....I bought the cam because it's only $250 and I know what I have. Getting a nice set of heads will out perform the stock ones and should be problem free for a long period of time. Also, I'd rather invest cash into new heads rather then into the old ones that are lower performing. I want to stay away from getting into the block/pistons etc... top end I can deal with, lower end.....is going to cost a lot more cash.

Plan A is still the one to go with at the moment. Take the bitch apart and see what's wrong, after a leak down test. Tester should be in today. Cam should be in later this week. Engine will be apart this weekend.

Thanks guys, don't give up on me yet.....

FU&* me!

When it rains it pours I guess. I missed the shop today and didn't get my tester. With a "free" night in the shop with no one to bug me, I thought I could get something done. Well, I fired up the stove and grabbed a few beers and headed out anyway. I figured I'd pull the spare engine out and start preparing it for a swap if need be. I hauled the valve covers off, pulled the intake and started inspecting....I put a ratchet on the front of the crank and inspected the cam and lifters all working until................................yep, you guessed it. #1 intake lobe is down to a near lump compared to the rest. I simply cannot believe my luck.

It's your money (which you said you're trying to save). Assuming your existing heads have issues, they can most likely be fixed for less than $500...or stuff the new cam in the spare engine....or swap heads from the spare to your existing engine. Good luck with whichever choice you make.

I have been thinking about all of the above. I have tomorrow off, and the weekend to start into this mess.

I just like having options....
