Finnally after changing from building a 4.6 to 5.0 then 5.0 to 5.8 i have decided not the totally destory my car and do that so I am going to build a 4.6 Liter SOHC. Here are a few things I have questions about:

1. Does anyone make a bellhousing to go 4.6 to T-5 (not T-45)?
2. I will be deleting the AC any thing i should know about doing this?
3. Which motor is better to build for a blower NPIw/PI C/I or NPIw/PI H/C/I?
4. Who has the Best/Cheapest Forged Bottom End?
5. Best Compression Ratio for a 4.6 w/Blower?
6. And Take answer from question 3 and tell which cams to get

Thanxs

It sounds like you still have a TON of research to do. You havent mentioned any variables besides wanting to go blown.

NPI Block

Edit:
And All I Need Is Forged Rods/Pistons. Stock Crank Will be fine for 375-450hp

2. there is a FRPP kit. it's basically just an idler pulley i believe.

3. depends on your hp goal and your $$ situation. the best is PI heads race ported with valves and springs, supercharged race cams, and ported bullit intake.

4. you can get a rotating assembly from Steeda for about $1900, but you have to have your block bored and assembled. you are better off buying a complete forged shortblock from a retputable vendor. about $3000 complete.

5. 8.5-9.0.

6. depends on what blower you get.

anyone know anything about 4.6 to T-5 Swap. I thought the t-45 and t-5 where almost the same anyway so it should work right?
