Mild 351 Build Opinions

I have searched and searched threads/posts but some final opinions on my possible build. Long story short my SAS once again has to be put on hold. I am in the middle of my paint/body work and have the front clip off. So I might as well and pull the engine to fix the oil pan and rear main leak. But why do that when I can freshen up my engine. Runs good with 188,000, just leaks fluid and would like a little more oomph. I need to keep cost down to because I am also doing the paint etc, so I figured on this: BBK under drive pulleys; GT40P heads; Edlebrock truck Performer lower/upper intake; stock cam; new oil pan/pump etc, water pump, 2 row radiator; freeze plugs and obviously gaskets.

I already have FMS headers, aftermarket Y pipe with single high flow cat and Magnaflow muffler. I figure as long as the compression and cylinder walls looks good I can squeeze another 20K miles or more until I have to bore her.

Maybe I can also get close to 300hp and some wanted Tq. I don't think I would be to far off but just probing your minds!

Thanks in advance!

im not a big fan of underdrive pulleys. but the upgrades you mention sound good. i personally want to get the edelbrock heads and truck intake manifold. brand new and complete bolt in. maybe do a rebuild kit since you are already going to take the top end off. why do the work twice. its more money, but you wont have to take it out again

will those headers work with the funny spark plug angle on the gt40p's?

I also wonder if an aftermarket cam that is SD friendly would be worth it. They aren't too expensive.

id rather do those than the edelbrock because it can save me some money but either way, the intake will be swapped

Something to consider...altough not "Cheap".....buy a tweecer or quaterhorse tuner and learn how to tune your fuel injection. Especially with the mods you are doing, you can get some more power and gas mileage out of a good tune. Or pay a reputable shop to tune it.

If you are going to go bigger, consider buying the parts to do a MAF swap...

Thanks for the all the valuable information and options. NO UNDERDRIVE PULLEYS!!!!! Got it! I was on the fence about it bit figured it might free up some horses/torque but see why not to do it.

I was looking at Professional products Typhoon intakes too, but there not much cheaper than Eldebrock setup. I might have to look more into the Typhoon lower and check prices.

I wanted to do a 393 MAF, but the time is here now and MAF will wait. I am crunching numbers for what I can afford and go from there. A 357 is what I am shooting for, but money will dictate. Also finding a affordable machine shop that knows what there doing is also being a challenge.

Thanks again for steering me in the right direction.

Tweecar or and tuner wont work on his computer. He doesn't have a MAF. Atleast from my searchs, I havn't found any tuners for a speed density.

Some speed density computers have the stratagey broken out, but not all. Those that don't, you can pay afew different people out there to break them out. Nearly any EEC 3 or 4 at this point can become tuneable

I am going to stay SD now and save the tuning and MAF for later. I just need to get my truck back together in a reasonable amount of time.

I think i am down to the GT 40 or 40P's now. Just have to look more at the smog crag and air pump setup. Then look at pistons and find a machine shop up here in BFE MT.

How much does everyone think a 357 short block would cost on avg? $1000?
Havent dealt with engines much and will continue to search in the forums and around town, but looking for ballparks so I can get this moving!!

Ok last question for awhile. Hopefully! So after reading, GT40Ps are a little better but more then likely won't be able to run the smog airpump. I can't just delete that correct? I have to re route it? I read it somewhere and have to find it.

Other the that and drilling out the bolt holes it's a plug and play, correct?
I will keep on searching the forums, just checking to see if I am correct so far.

After picking the headS I will go on to the pistons and then everything is easy.

the 96 explorer 5.0 gt40 heads have standard sbf exhaust ports. i say throw a mild cam in there while you have it apart mine is pretty much the same except its carbed edelbrock carb and intake though and when i had mine on 33s with 3.50 gears i couldnt launch hard in 2nd (zf5 trans) because it would spin the 11in heavy duty clutch so it has plenty of power
just my $0.02 worth

I almost have the game plan buttoned up. I have been talking to my machinest who is doing my balancing, porting etc. and he has convinced me not to by GT40P heads. Even though I am on fairly tight budget, it makes sense. Spend a little more now and be happy in the long run. So I am down to these heads in order. I want to keep it close as possible to a 9.5 compression ratio. I will be running on SD, stock cam, Edelbrock truck performer intake, FMS headers, Bassani Y pipe, with cars and Magnaflow muffler.

Trick Flow 170cc twisted wedge
GT40X- (Gacknar had good luck with these)
Edelbrock RPM heads
