Lightning and 95 R Blocks
I am going to assume that the First Gen Lightnings and 1995 Cobra R's used the same style block even though they used different intakes and accessories.
My main question is about the cams. Are they flat tappet or roller, specifically for the 95 R?

Re: Lightning and 95 R Blocks
Good question, I had never thought about the R's but the lightning's are non-rollers.
Pretty sure they are not. Just read in my cobra guide that they started life as a 305 marine engine which was a 351w block with a shorter stroke. They up'd the stroke to a 351 and kept the 'marine' cam in them

SVT says that the 93-95 Lightnings were 4in x 3.5in motors with 8.8:1 compression. Then the 95 R's were 4in x 3in motors with 9.0:1 compression. So that right there tells me they are not the same "configuration", but it seems that SVT would use a roller cam for reliability and power production.

If you don't belive me, do the math of a 4" bore and 3" stroke motor; it comes out to be 301.59".

Never use that site as accurate info. They have a few screwed up details on 93 cobra. They have been contacted about it and refuse to fix it.

Re: Lightning and 95 R Blocks
Remember late model year 93 Lightning engine blocks have the bosses for a roller, but no roller cam was ever used in the 93-95 Lightnings.
The bosses need to be drilled and tapped then the spider out of a 302 will bolt right in. The reason you dont see more Lightnings converting over to roller is that a good roller will cause big problems with the speed density computer.
