Another 408/f1r build
 

So awhile back I purchased an F1r kit off. Some should be familiar as MR2LITERs old setup. Well a little info on my setup. I have a 408 w stock ls3 top end(ls3 heads milled.030) stock ls3 fuel rails in this setup 3" y pipe into a y merge 3" -4" out to a 4" cutout then reduced back to 3" out, will be studding the block with ls9 headgaskets, 2 bar map sensor, chris1313 dual fuel pumps, 210 injectors, 8an feed line and using stock feed line for return. The kit came with a 7.65 crank and 4" blower pulley. Came with 3.5 twin intercoolers w tial q 50mm setup I know this will be a massive restriction but it's all I can afford for now. Cam spec is stroker cam 242/248 .636/.636. Looking into an alky kit as my kit came with the pump already. How many lbs are yall thinking I'll be able to achieve, whp #s

:bang:

Any updates? Im building a similar 402 setup and am curious about results!

Nothing yet going to be about a month till finish just seeing what up on people opinions getting info about where I will stand. Bob told me to go to a 5.25 pulley because the f1r will get the twins really hot with a 4" pulley
