find a 96-99 cobra motor for cheap, it comes with a teskid block and if you put good internals it'll take almost anything you throw at it.

other than the GT supercar heads the 03-04 cobra C heads are the best flowing but B heads can be made to make decent power

+1, the WAP block in some of the 01s and Machs are good if you're not going to go crazy. Machs have the same heads as 03-04 cobras. Only Manual machs came with the forged crank like all cobras. If you're going N/A intakes are Mach > 01 > 99.

I'm not sure what to do a this point anymore. This 4v swap is getting real expensive so I might go in the direction of a 351 with a 76mm turbo. I can make much more power that way for alot less money. I want to make around 750rwhp

If thats the case just buy one that already done.
I know its fun to do the work yourself but sometimes its much easier and less stressful to just open the checkbook.

I'm not sure a pushrod is any cheaper. 750 rwhp can be done with both engines, but the way I look at it, you can do that with a 4v motor with a stock aluminum block, that by the way you can pickup for about $200. Stock heads, shit even b-heads and if your doing turbo a lot of guys say b-heads are the way to go. You can pick those up for less than $100 sometimes. You can use stock 96-98 cams, stock intake. You can't use any of that cheap stock stuff if you did a pushrod motor.
