the collector on the headers should not drag unless you are lowered a ridicuolous amount.

and i am in the same boat as you as i have a 69' block and converting to a hydraulic roller with link bar lifters would be the way as then u will have a lot bigger cam choice to pick from , also they are a better,faster revving setup when setup right in the valve train.

i guess what do u want the car to do? also if u are already dumping afr 185's on it i would look around for a good used set of link bar lifters and do it that way, as i am on the hunt for a set right now myself.

I just want a solid, streetable and reasonably or unreasonalby fast car. I had all the parts to build a 302 and had a block all ready to go, but my buddy needed it, so I sold it to him. Came across this 351 and couldn't pass it up....so here I am, learning how to make this work.

Guess I need to make up my mind as far as making it a roller motor.

So...here is my next question. I have long tube headers from my 302 build. I have installed a QA1 K-member. I heard once that if you use convertible motor mounts, that it will make the motor sit lower, any truth to this that you know of? And if so, do you think its enough to use the 302 long tubes?

im not sure on the 302 to 351 longtubes..

1995 blocks are roller capable out of the box. they still use flat tappit's however. you can use your 302 roller parts for the conversion (lifters, dogbones, retainers). look for a f4te casting number. 1996 and newer 351w used the same block but came from the factory with roller cams.


the issue i see is the large valves on the afr 185 heads being an issue with stick pistons. check to see if there is sufficent valve clearence on the motor. this is where the 165's are used (same flow but they used smaller valves)

Use bbk long tubes. My dad has them on his car, i love them. If it is going to cost you too must money to convert to roller, dont do it. You will still make over 350whp regardless with your setup, more depending on cam selection.

There are better heads out there for about the same ammount of money. I would do some research.

only solid motor mounts will gain u any kind of hood clearance. and its about 1".. thats what i used on making my stock work on my 88 gt 351w

i am using an x-cam .544 lift with 1.7 rockers = .582 lift on stock lightning shortblock w/ 2.02 valves its all in the cam profile and timing as to wether the pistons will give the valves a kiss or not.
