302 Gurrus needed

Cant use standard roller lifters your block does not have provisions for the spider tray and dog bones that keep them from spinning in there bores. You have 2 choices #1 use your block and link bar lifters ($300+) small selection of cams. #2 get a roller block lifters run $120 huge selection of cams for that block and they have a little thicker cylinder walls.

I would want to know when decking the head surface do they do it off the oil pan rail (old school) its ok but i prefer it to be done off the crank centerline insures heads are paralel to crank not the pan. If they will be honing the cylinders for you. Check to see if its done to spec. for the rings you are going to use. And if its done with a torque plate (rings seat faster) and always ask for a tour of the shop i avoid the shops that are dirty with crap everywhere. You might want to go to fordstrokers.com and look at shop and equipment to know what an up to date shop looks like.

Same bore and bore spacing for the 302 and the 351, same heads bolt pattern but the intake is different in width and one water passage needs a look at.
The Edlbrock Package is good and the Holley Package is good also.
Not sure if TrickFlow makes a package or not but what going to big on the heads, it can defeat you fast.
From what I have heard the Edlbrock Package has more low end torque… that’s the stuff that gets you going and the more of it the more kick in the @ss you will feel when starting off.
IMHO... first decide what you want to do with the Truck.
Then contact a Manufacturers Site and ask a Tech what they have and what Torque/HP will come out of it and WHAT is required to get to the Torque/HP you want.
You might even change up the cam for something with a little more lift, keep the short duration and make sure the pistons can handle the lift you are going to but if you contact the company direct they can help to set up what you want.
Luck,

Ya i already was in contact with TrickFlow. There kit is heads cam, upper and lower intake the whole nine yards. and they say that it will make 370 lbs trq and 360 Hp.Only thing is tho is that the kit that they make is for the mustang that has the roller cam. I have the flat tappet. is it possibly to machine my block so that it will accept the roller cam.

The Cam has a different Lobe spread, can’t remember what it is but the I think 112 degrees for the EFI, wider than the Flat Tappet.
The block on a 5.0L is setup for the Roller Lifters, that is the problem, there is a kit for older 5.0L Ford to adapter the Roller Lifters to the Flat Tappet Block.
Edelbrock did have the best numbers for the lower end remember that’s important.
A buddy of mine just used the Edelbrock Heads and they really made a big difference in his 5.0L Stang.
IMHO… unless you are building a truck for the drags, think seriously about Edelbrock setup.
Trick Flow does have larger Valves, two problems higher RPM use to get the flow out of them and you lose on low end.
Edelbrock heads have a little smaller valve than the Trickflow, could be why they have better low end numbers.

Once you have determined what you have and where you want to be after the Cam is installed it is best to contact the Manufacturer of the Cam to make sure all of the parts will work together. The manufacturers have programs that take all of the data, engine, weight of vehicle, what you want to do with it and make a determination on the best package for you.
I think he is referencing the Cam Gear, Replace the Gear that bolts on the end of the Camshaft. You will see it once you remove the Water Pump Housing/Timing Chain Cover. It is a good idea to replace both with the new Cam and the Gear that is on the end of the Crankshaft as a set; they even make Roller Chains if you want one.
All three parts, the Cam Gear, the Crankshaft Gear and the Chain can be purchased as part of a set or the complete package.
Again I say the same thing, I know repeating myself, “Start by determining what you want to do with the vehicle”. From there contact a manufacturer, like Edelbrock and ask them what is there suggestion; use there expertise and engineering skills to get the best package for you.
Sometimes it is better to use a kit with everything working together.
